EC-E...

Data sheet

1Description

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 I

N

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.

Wiring and signaling tasks can be implemented easily using

power rails and plug-in bridges.

A multi-color LED and the integrated status output display

the operating and fault state.

The miniature circuit-breaker has a design width of 12.5 mm

and can be snapped onto NS 35 DIN rails using a modular

approach. It is equipped with screw connections.

Properties

–

Selective load protection, electronic shutdown

characteristic curve

–

Active current limitation when switching on capacitive

loads of up to 20, 000 µF and in the event of an

overload/short circuit

–

Nominal current can be selected in fixed current

strengths from 0.5 A ... 12 A

–

Safe overload shutdown from 1.1 x I

with long load lines or small cable cross-sections

–

Manual on/off switch (S1)

–

Clear signaling by means of LED, SF status output, or F

alarm output (signal contact), (can be combined)

–

RE electronic reset input (option)

–

Integrated fail-safe element, adapted to nominal current

–

Straightforward wiring using LINE+ power rail and 0 V,

as well as signal rails and signal bridges

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.
