Description

The ECP-E3… 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-E3… electronic circuit breaker,

which selectively protects all 24 V DC load circuits. The

ECP-E3… 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.

In addition, the ECP-E3… can be reset by means of the

reset input (12), for example, via a PLC, i.e., the ECP-E3…

is electronically reset by means of a falling +24 V DC edge

(at connection 12).

The floating auxiliary contacts of the ECP-E3… can be used

to implement a group query from connection 13 to 14.

If a circuit breaker trips or is disabled, the signal to

connection 14 is interrupted.

A multi-color LED and the integrated status output

(12) indicate the operating or error state.

The ECP-E3… 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.
