Description
The ECP-E… electronic circuit breaker can be used in
applications that cover all aspects of the switched-mode
power supply unit.
In the event of an overload, switched-mode power supply
units reduce their output voltage, which means that all the
connected loads are no longer sufficiently supplied, e.g., in
the event of a short circuit at the load.
The solution here is the ECP-E… electronic circuit breaker,
which selectively protects all 24 V DC load circuits. The
ECP-E… constantly limits the residual current to 1.8 times
(or 1.5/1.3 times) the protected nominal current. Capacitive
loads can thus be switched on and loads are only switched
off in the event of an overload or short circuit.
After detecting an overload or short circuit in the load circuit,
the load output of the ECP-E… is disabled. The current flow
in the faulty circuit is interrupted. The ECP-E… and therefore
the circuit can be activated again via the electronic reset
input (13;14) or manually on the device via the slide switch.
A multi-color LED and the integrated status output (12)
indicate the operating or error state.
The ECP-E… offers quick and space-saving assembly, as it
can be plugged onto the TMCP SOCKET M and has a low
design width of just 12.5 mm.

In the system or machine, take special precautionary measures to prevent system parts from restarting (according
to Machinery Directive 2006/42/EC and EN 60204-1). In the event of an error (short circuit/overload), the load
circuit is electronically shut down by the ECP-E….
NOTE: Make sure that the cable cross-section of the relevant load circuit is adapted to the nominal current of the
ECP-E… used.
Make sure you always use the latest documentation.

Time-current characteristic
In the 1.1 ... 1.8 x IN* range, the typical shutdown time
is 3 s.
The electronic current limitation is typically activated
from 1.8 x IN*.
This means that under all overload conditions
(regardless of the current supply and load circuit
resistance), 1.8 times the nominal current* typically
flows until shutdown. The shutdown time ranges from
100 ms to 3 s depending on the multiple of the nominal
current or in the event of short circuit (IK).
Without the current limitation typically activated at
1.8 x IN*, a significantly higher overcurrent would flow in
the event of an overload or short circuit.
Typical current limitation 1.8 x IN at IN = 1 A ... 6 A
Typical current limitation 1.5 x IN at IN = 8 A or 10 A
Typical current limitation 1.3 x IN at IN = 12 A

Shutdown current Ioff = 3 A x 1.25 A = 3.75 A
Maximum circuit resistance Rmax = UB/Ioff - 0.050 (internal resistance of miniature circuit breakers)
Rmax = (19.2 V/3.75 A) - 0.050 = 5.07
In the table, the calculated value of 5.07 lies between 200 m and 225 m (4.75 and 5.34 ).
Therefore a distance of around 200 m can be covered.

Mounting on a modular base
The TMCP SOCKET M base is snapped onto a DIN rail and
can accommodate two ECP-E… devices.
The two-channel bases are modular, which means that
larger distribution systems can be created. A connection
element is inserted at both the start and end of the system.
Current distribution on the individual channels with a
common supply (positive pole) is achieved by inserting a
power rail in the slot provided on the connection side of the
modules.
All electrical connections are established using spring-cage
terminal blocks. The reference potential for the ECP-E…
(GND pin 11) is also looped through and led to the side
connection elements.
By connecting together the individual bases, all the internal
wiring is established for the ground potential and group error
message.
The ECP-E… has an integrated signal contact (PDT). The
SC-S0 contact is used for the group error message. The
contacts for this indication are already connected in series
in the bases and are connected to the side connection
elements via two connections (13, 14).
In each base, the series circuit can be contacted using a test
socket and any interruptions can thus be determined.
