EV RELAYS (DC Contactors)
High voltage DC, High capacity Cut-off Relays using Capsule Contact Mechanism
FEATURES
1. Compact, lightweight and safety
To realize quick gap cutoff with high voltage DC, hydrogen gas, which has superior arc cooling
capability, is sealed in the capsule contact chamber. At the same time, superior safety is achieved
owing to an airtight construction that prevents arc leakage.
2. High contact reliability
Since the contact portion is sealed in hydrogen gas, there is no contact oxidation. It is also dustproof
and waterproof.
3. Richly varied lineup
Types that are quiet in operation types and high short-circuit capacity types are also available.
Moreover, the lineup includes plenty of all plug-in types, as well as high carrying current types.
APPLICATIONS
1. Electric vehicles (HEV, PHEV, BEV, and FCV)
2. Battery charge and discharge systems
3. High voltage DC applications such as hybrid construction

NOTES
Safety precautions
If you continue to use a product in a poor condition, items
with deteriorated insulation performance may generate
abnormal heat or smoke or even ignite. The product's failure
or end of service life may cause accidents involving risks to
human health, fire, or danger to the public at large. We advise
you to apply safety measures and regular maintenance work,
such as the use of redundant design, fireproofing, and
malfunction-preventing design, to rule out such accidents.
We are doing our best to constantly improve the quality and
reliability of our products. However, some electric
items/components do in fact fail despite our efforts.
The durability of products also varies depending on service
environments and conditions. Please check your product
under actual service conditions before use.
For general cautions for use, please refer to the "Automotive Relay Users Guide".
Precautions when using EV relays
Usage, transport and storage conditions
1. Ambient temperature, humidity, and air pressure during
usage, transport, and storage of the relay
(1) Ambient temperature: –40 to +80°C
(200 A and 300 A types: –40 to +85°C)
(2) Humidity: 5 to 85% R.H.
(Avoid icing and condensation.)
(3) Air pressure: 86 to 106 kPa
2. Water condensation
Water condensation occurs when the ambient
temperature drops suddenly from a high temperature and
humidity, or, the relay is suddenly transferred from a low
ambient temperature to a high temperature and humidity.
Condensation causes the failures like insulation
deterioration, wire disconnection and rust etc. Panasonic
Corporation does not guarantee the failures caused by
condensation.
3. Low-temperature, low-humidity atmosphere;
If the relay is exposed to a low-temperature, low-humidity
atmosphere for a long time, its plastic parts may become
brittle and fragile.
4. Storage
Do not keep under high-temperature and high-humidity.
Note: The humidity range varies with the temperature. Use within the range
indicated in the graph below.
[Temperature and humidity range for usage, transport, and storage]
When installing the relay, always use washers to prevent the
screws from loosening.
Electrical life
This relay is a high-voltage direct-current switch. In its final
breakdown mode, it may lose the ability to provide the proper
switch-off. Therefore, do not exceed the indicated switching
capacity and life.
(Please treat the relay as a product with limited life and
replace it when necessary.)
In the event that the relay loses switch-off ability, there is a
possibility that burning may spread to surrounding parts, so
configure the layout so that the power is turned off within one
second.
Condition of tightening screw
Tighten each screw within the rated range given below.
Exceeding the maximum torque may result in breakage.
Mounting is possible in either direction.

Permeation life of internal gas
This relay uses a hermetically encased contact (capsule
contact) with gas inside. The gas has a permeation life that is
affected by the temperature inside the capsule contact
(ambient temperature and temperature rise due to flow of
electrical current). For this reason, make sure the ambient
operating temperature is between –40 and +80°C (200A and
300A types: Max. +85°C), and the ambient storage
temperature is between –40 and +85°C.
2.2 to 2.8 Nm

The coils (300A type) and contacts (except compact high
short-circuit capacity type) of the relay are polarized, so
follow the connection schematic when connecting the coils
and contacts.
The 300A type contains a reverse surge voltage absorption
circuit; therefore a surge protector is not needed.
Nominal cross-sectional area
For the 300A type, drive the coil with a quick startup (apply
100 to 130% of rated coil voltage in less than 10ms). (Built-in
one-shot pulse generator circuit)
10A type
Min. 2 mm2 nominal cross-sectional area
20A type
Min. 3 mm2 nominal cross-sectional area
60A, 80A types
Min. 15 mm2 nominal cross-sectional area
120A type
Min. 38 mm2 nominal cross-sectional area
200A type
Min. 60 mm2 nominal cross-sectional area
300A type
Min. 100 mm2 nominal cross-sectional area
As a guide, the insertion strength of the plug-in terminal into
the relay tab terminal should be 40 to 70N (10A type), 40 to
80N (20A and Quiet horizontal types). Please select a plug in
terminal (flat connection terminal) which comply with JIS
C2809-2014.
After the ON signal enters the 300A type, automatic coil
current switching occurs after approximately 0.1 seconds.
Do not repeatedly turn it OFF within that 0.1 seconds interval,
as doing so may damage the relay.
Be careful that foreign matter and oils and fats kind don’t
stick to the main terminal portion because it is likely to cause
terminal portion to give off unusual heat.
Also, please use the following materials for connected
harnesses and bus bars.
10A type
Plate thickness 0.5mm and #187 tab
terminal
20A, Quiet horizontal types
Plate thickness 0.8mm and #250 tab
terminal
Avoid excessive load applied to the terminal in case of
installing such as a bus bar etc., Because it might adversely
affect the switching performance.
Use the specified connector for the connector terminal
connection (80A, 120A and 300A types).

Other cautions for use
1. Please make sure to contact our sales representative
when the product is used not in accordance with its
specifications. Your nearest sales office staff will review
the required specification from your company and
perform confirmation tests in actual condition as needed.
2. When the voltage is applied to the relay coil beyond the
max. allowable voltage range, the relay operation cannot
be assured. Additionally the ambient temperature and
condition of your application should be considered under
the worst condition of the actual usage because they may
change the relay operate and release voltage.
Ex. 2 When Zener diode (circuit) is used
［1］
［2］
Note: It is not allowed to apply the continuous maximum voltage to the coil. In order
to obtain the specified performance, please apply the rated voltage.
3. If it includes ripple, the ripple factor should be max. 5%.
In addition, do not have a parallel connection with diode
for the purpose of coil surge absorber. If only diode is
connected in parallel to the relay coil, break performance
of relay cannot be assured because contact release speed
becomes slower. So do not use such a circuit. Instead of
diode, a Varistor (ZNR) or Zener diode (ZD) when clamp
voltage is 1.5 times larger than the rated voltage (Min.
18V for the rated 12V-relay), shall be used for the
absorber.
Ex. 1 When Varistor (ZNR) is used
Recommended
Varistor
Varistor Voltage
4. Lifetime is specified under the standard test conditions in
JIS C 5442. (temperature 15°C to 35°C, humidity 25% R.H.
to 75% R.H.)
Lifetime is dependent on the coil driving circuit, load
type, operation frequency and ambient conditions.
Check lifetime under the actual condition. Especially,
contact terminals have polarity. So if the contact
terminals were connected with opposite pole, the
electrical life would be shortened.
We can not guarantee the relay's quality in case the relay
is operated without load current (Dry-switching).
5. If the relay is dropped, it should not be used again.
6. Please contact our sales representative when AC load
gets applied to this relay. Careful handing is required for
switching AC load with this relay.
Energy capability: Min 1 J
(However, please set up the value with consideration of
the worst value in use condition.)
Min. 18 V at 12 V DC
Min. 36 V at 24 V DC

7. Please check the internal connection diagram in the
catalog or specification, and connect the terminals
correctly. If any wrong connection is made, it may cause
circuit damage by unexpected malfunction, abnormal
heat, fire, and so on.
8. Please check the insulation distance between each
terminal and ground.
9. Please assure the evaluation of the relay under the actual
worst condition to enhance the reliability for the actual
usage.
10. Please absolutely avoid the ultrasonic and high frequency
vibration to the relay that adversely affects its
performance.
11. Minimum switching load is the lower limit switching
current under the micro-load.
When the relay is used below minimum switching load,
reliability becomes lower. Please use the relay beyond
minimum switching load. Additionally, minimum
switching load is changed by coil drive circuit, type of
load, switching frequency and environment condition. So
please confirm the reliability with actual load under the
assumed actual environment.
12. As for the screws of fixing relay-body and screws of fixing
contact terminal, the tightening torque must be within the
specified range.
• The purpose of the tightening torque for the contact
terminal is to secure adhesion force (axial force) at the
fixing part and provide stable electrical connection.
Therefore, do not use the screws (bolts and nuts) which
require rotation torque of locking type (prevailing
torque type) because sufficient adhesion force (axial
force) may not be secured.
In addition, if the locking type nut is used, an excessive
torque may be applied to the case before generating of
axial force and may cause breakage of the case.
• Regarding the screw for fixing relay body, please use
suitable screws after adequate verification at user’s
side.
13. The relay should not be installed near strong magnetic
fields (transformers, magnets, etc.) and should not be
installed near heat source.
14. If the several relays are mounted closely or a
heatgeneration object is close to the relay, it may cause
troubles the abnormal temperature-rise and the short
insulation distance terminals outside of the relay so
please assure the evaluation of the relay under the actual
worst condition.
15. The relay contacts are encapsulated in an inert gas
atmosphere. So, please avoid using or storing beyond the
allowable ambient temperature range.

16. After that the relay has been applied with the rated
voltage and current to the coil continuously and then the
relay is once switched off and switched on immediately,
the relay coil resistance may be increased due to the coil
temperature increase. This will result in higher operate
voltage and the value will surpass the rated operate
voltage value. In order to avoid this failure, the following
countermeasures are recommended.
• decrease of the load current
• restriction of time to apply voltage
• restriction of operating ambient temperature, etc.
17. If an inductive load (L/R > 1ms) is applied, add surge
protection in parallel with the inductive load. If this is not
done, the electrical life will be shortened and cut-off
failure may occur.
18. In case using a capacitive load (C-load), please take a
countermeasure as pre-charging to the capacitive load so
that the inrush current will not surpass performance
condition. The relay may have a contact welding without
such countermeasure.
19. Use the suitable wire or bus bar according to the current.
If the wire diameter is thin, maximum allowable contact
current cannot be assured.
Ex.) Carrying current; 120A: diameter of 38mm2
(minimum) (for wire at the load side)
20. Take care to disconnect from the power supply when
wiring.
21. The tension load applied to the coil lead wire when wiring
should be max. 10N.
In addition, take care not to bend at the lead wire pullout
portion when wiring or apply a stationary load to the lead
wire after wiring to avoid failure of the relay such as
breaking of wire.
(only applicable to the relay with the coil lead wire)
22. The relay satisfies water resistance level of JIS D 0203 R2.
Please take any countermeasures additionally if it is
installed in the place where higher water resistance level
is required.
23. Do not use this product in such atmosphere where any
kind of organic solvent (as benzene, thinner and alcohol)
and the strong alkali (as ammonia and caustic soda) may
be adhered to this product.
24. Be careful that oils and foreign matter do not stick to the
main terminal part because it is likely to cause a terminal
part to give off unusual heat.
25. Do not make additional manufacturing upon the relay
housing.
26. Maximum overcurrent value in this specification is limited
as single operation only. In the case of multiple
operation, this relay may cause malfunction by heating.
So, please confirm the temperature / operation using
your application. In the case of multiple operation, please
stop applying the over current to secure the relay's
temperature under the maximum ambient temperature.
27. When applying current which includes precipitous
changes or ripple, the relay may generate buzzing sound.
Therefore, please confirm with the actual load.
