Automation Controls Catalog (10A and 80A types) *20A type: only UL (Recognized) 200A type has been added. High Capacity of Max. 1,000 V DC Cut-off Possible FEATURES Protective construction：Sealed capsule type 10A PC board type 10A TM type 20A TM type 200A type 80A type 300A type 1. High-voltage, high-current control capable 1,000V DC switching has been achieved thanks to a sealed construction with mixed hydrogen gas and the magnetic arc motion through use of a permanent magnet. 2. Compact & Low Operating Sound By using a capsule contact mechanism that is enclosed with hydrogen gas, highcapacity cutoff is possible even with a tiny contact gap. There is little operating sound, which does not change even when large currents are cut off. 3. Arc space unnecessary The enclosure box can be made smaller thanks to an arc-space-free construction from which the arc will not get out. 4. Safety Since the contacts are enclosed in a sealed capsule structure, the arc will not get out, which ensures safety. 5. High contact reliability The contact part is hermetically sealed with H2 mixed gas, hence the contact resistance remains stable regardless of the ambient conditions. 6. Mounting direction is not specified EP RELAYS(AEP) The weight of the movable parts is light, and also the restoring force is large, hence the relay is relatively unaffected by gravity. 7. Wide selection of models available Types include PC board type (10A), TM type (10A and 20A), Lead wire type (200A) and Connector type (80A and 300A). 8. Standard compliance The 10A, 20A, 80A type is UL/C-UL standard certified. TYPICAL APPLICATIONS 1. Photovoltaic power generation systems 2. Cogeneration systems 3. Construction machinery 4.

In these circumstances, take 10A TM type: measures such as reducing the load #187, 0.5 mm board thickness 20A TM type: current, limiting the duration of current flow, and applying a coil #250, 0.8 mm board thickness tab terminal (JIS C289-1999 compliant, voltage higher than the rated flat type connection terminal) operating voltage. 10. Pure DC current should be applied to the coil. If it includes ripple, the Harness nominal cross-sectional area ripple factor should be less than 5%. Load input terminal side; However, check the actual circuit 10A TM type: min. 2.0 mm2 since the characteristics may be 20A TM type: min. 3.0 mm2 slightly different. The power supply 80A type: min. 15 mm2 waveform supplied to the coil should 200A type: min. 60 mm2 be rectangular. Also, the 300A type 300A type: min. 100 mm2 has a built-in dedicated drive circuit. It Coil input terminal side; 10A and 20A TM may not operate normally unless the types: min. 0.3 mm2 rise time is 10 ms or less. 16. Use 40 to 70N or 50 to 80N of force 11. Don’t exceed maximum coil as a guide to fasten the terminal voltage. Exceeding maximum connected to the 10A TM and 20A TM types. Please use caution when allowable coil voltage on continuous basis will damage the relay and could inserting or removing the terminal as case failure. the relay tab terminal may cause If you will be using with a load injuly. Also, unstable conductivity and 12. voltage that exceeds 400 V DC, please abnormal terminal heating may occur; therefore, please check that there is be sure to verify operation on the actual device, referring to the no deformation of or foreign objects switching life curves (reference data). on the faston terminals (blade You must absolutely avoid continual receptacle) you will be connecting. Use JIS C2809 (or IEC60760) certified use in which the load current exceeds products. the rated value. This will cause abnormal heating. 13. The rated control capacity and life are given as general guides. It is important to conduct sufficient tests on the actual device, because contact properties and working life will differ considerably depending on the type of load and conditions. 17. Place the PC board mount type (10A PC board type) securely by hand soldering after attaching it using M4 screw. Don’t submerge assembled board in cleaning solvent or water. Also, be careful not let flux overflow up from the PC board or adhere to the base of the relay. Recommended hand soldering conditions • Soldering iron: 30 to 60 W • Tip temperature: 400°C 752°F • Solder time: within approx. 5 seconds 18. Make sure the power is turned off when wiring. 19. Incorrect wiring may cause unexpected malfunction and failure. 20. Regarding AC cutoff, although there is no contact polarity, generally it is thought that the electrical life will shorten due to cutoff in the reverse direction, compared to DC cutoff. Confirm electrical life using actual load. In the case of DC cut-off, please note the contact polarity. 21. Lead-free solder (tin, silver and copper) is used as pre-solder for the terminals of the PC board mount type (10A PC board type). 22. The warranted tensile strength of the female connector lead wire used for connection that comes with the 80A and 300A connector type when attaching it to the relay body is 98N. Avoid excessive tension as this is a cause of broken wires and damage. Also, insert the female connector deeply and make sure the connection is secure. 23. Condensation will occur during sudden temperature changes in hot and humid environments. Caution is required, because condensation will cause a decrease in the insulation resistance between the terminals. 24. Please note that if the 80 A type is used only with excessive load, the contact resistance may possibly increase.

(circuits for emergency lamps, alarm devices and error inspection that, for example, revert only during malfunction and output warnings with form B contacts) Continuous, long-term current to the coil will facilitate deterioration of coil insulation and characteristics due to heating of the coil itself. For circuits such as these, please use a magnetic-hold type latching relay. If you need to use a single stable relay, use a sealed type relay that is not easily affected by ambient conditions and make a failsafe circuit design that considers the possibility of contact failure or disconnection. Proper usage requires that the rated coil voltage be impressed on the coil. Note, however, that if a voltage greater than or equal to the maximum continuous voltage is impressed on the coil, the coil may burn or its layers short due to the temperature rise. Furthermore, do not exceed the usable ambient temperature range listed in the catalog. Operate voltage change due to coil temperature rise (Hot start) In DC relays, after continuous passage of current in the coil, if the current is turned OFF, then immediately turned ON again, due to the temperature rise in the coil, the pick-up voltage will become somewhat higher. Also, it will be the same as using it in a higher temperature atmosphere. The resistance/temperature relationship for copper wire is about 0.4% for 1°C, and with this ratio the coil resistance increases. That is, in order to operate of the relay, it is necessary that the voltage be higher than the pick-up voltage and the pick-up voltage rises in accordance with the increase in the resistance value. However, for some polarized relays, this rate of change is considerably smaller. DC Coil operating power Steady state DC current should be applied to the coil. The wave form should be rectangular. If it includes ripple, the ripple factor should be less than 5%. However, please check with the actual circuit since the electrical characteristics may vary. The rated coil voltage should be applied to the coil and the set/reset pulse time of latching type relay differs for each relays, please refer to the relay's individual specifications. Coil connection When connecting coils of polarized relays, please check coil polarity (+,-) at the internal connection diagram (Schematic). If any wrong connection is made, it may cause unexpected malfunction, like abnormal heat, fire and so on, and circuit do not work. Avoid impressing voltages to the set coil and reset coil at the same time. Ambient Environment Dew condensation Usage, Transport, and Storage Conditions 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. The heat conduction by the equipment may accelerate the cooling of device itself, and the condensation may occur. Please conduct product evaluations in the worst condition of the actual usage. (Special attention should be paid when high temperature heating parts are close to the device. Also please consider the condensation may occur inside of the device.) During usage, storage, or transportation, avoid locations subjected to direct sunlight and maintain normal temperature, humidity and pressure conditions. Temperature/Humidity/Pressure When transporting or storing relays while they are tube packaged, there are cases the temperature may differ from the allowable range. In this case be sure to check the individual specifications. Also allowable humidity level is influenced by temperature, please check charts shown below and use relays within mentioned conditions. (Allowable temperature values differ for each relays, please refer to the relay's individual specifications.) Icing Condensation or other moisture may freeze on relays when the temperature become lower than 0°C.This icing causes the sticking of movable portion, the operation delay and the contact conduction failure etc. Panasonic Corporation does not guarantee the failures caused by the icing. The heat conduction by the equipment may accelerate the cooling of relay itself and the icing may occur. Please conduct product evaluations in the worst condition of the actual usage. Low temperature and low humidity The plastic becomes brittle if the switch is exposed to a low temperature, low humidity environment for long periods of time. High temperature and high humidity Storage for extended periods of time (including transportation periods) at high temperature or high humidity levels or in atmospheres with organic gases or sulfide gases may cause a sulfide film or oxide film to form on the surfaces of the contacts and/or it may interfere with the functions. Check out the atmosphere in which the units are to be stored and transported. 1) Temperature: The tolerance temperature range differs for each relays, please refer to the relay’s individual specifications 2) Humidity: 5 to 85 % RH 3) Pressure: 86 to 106 kPa Humidity, %R.H. 85 Allowable range (Avoid icing when used at temperatures lower than 0° C) 5 –40 (Avoid condensation when used at temperatures higher than 0° C) 0 Ambient temperature, ° C 85 Panasonic Corporation Electromechanical Control Business Division industrial.panasonic.com/ac/e/ -1- c Panasonic Corporation 2019 ASCTB412E 201903 GUIDELINES FOR POWER RELAYS AND HIGH-CAPACITY DC CUT OFF RELAYS USAGE Package In terms of the packing format used, make every effort to keep the effects of moisture, organic gases and sulfide gases to the absolute minimum. Silicon When a source of silicone substances (silicone rubber, silicone oil, silicone coating materials and silicone filling materials etc.) is used around the relay, the silicone gas (low molecular siloxane etc.) may be produced. This silicone gas may penetrate into the inside of the relay. When the relay is kept and used in this condition, silicone compound may adhere to the relay contacts which may cause the contact failure. Do not use any sources of silicone gas around the relay (Including plastic seal types). NOx Generation When relay is used in an atmosphere high in humidity to switch a load which easily produces an arc, the NOx created by the arc and the water absorbed from outside the relay combine to produce nitric acid. This corrodes the internal metal parts and adversely affects operation. Avoid use at an ambient humidity of 85%RH or higher (at 20°C). If use at high humidity is unavoidable, please contact our sales representative. Others Cleaning 1) Although the environmentally sealed type relay (plastic sealed type, etc.) can be cleaned, avoid immersing the relay into cold liquid (such as cleaning solvent) immediately after soldering. Doing so may deteriorate the sealing performance. 2) Cleaning with the boiling method is recommended(The temperature of cleaning liquid should be 40°C or lower ). Avoid ultrasonic cleaning on relays. Use of ultrasonic cleaning may cause breaks in the coil or slight sticking of the contacts due to ultrasonic energy.
