Description
and can be snapped onto NS 35 DIN rails using a modular
approach. It is equipped with screw connections.
The EC-E... electronic miniature circuit-breaker selectively
protects all 24 V DC load circuits on power supply units. A
combination of active electronic current limitation for short
circuits and an overload shutdown function from 1.1 x IN
upwards ensures that the miniature circuit-breaker can
react to overloads faster than the power supply unit. In this
case, the residual current is constantly restricted to 1.3 -
1.8 times the nominal current.
This enables capacitive loads of up to 20,000 µF to be
switched on; loads are shut down only in the event of an
overload or short circuit.
Once an overload or short circuit has been detected in the
load circuit, the load output of the EC-E... is blocked. The
current flow in the faulty circuit is interrupted. The EC-E...
and, therefore, the current circuit can be activated again
using the electronic reset input or manually on the device
using the slide switch.

Straightforward wiring using LINE+ power rail and 0 V,
as well as signal rails and signal bridges

power rails and plug-in bridges.
A multi-color LED and the integrated status output display
the operating and fault state.
NOTE: Make sure that you adapt the cable cross-section of the relevant load circuit to the nominal current of the
EC-E... being used.
Take special precautions in the system or machine to eliminate the possibility of system parts restarting (in
accordance with the Machinery Directive 2006/42/EC and EN 60204-1). In the event of a fault (short circuit/
overload), the EC-E... shuts down the load circuit electronically.
Make sure you always use the latest documentation.
