Description
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.
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 IN upwards, even
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.

Time/current characteristic curve
In the 1.1 ... 1.8 x IN* range, the shutdown time is
typically 3 s.
The electronic current limitation function is typically
used from 1.8 x IN* upwards.
This means that, typically, 1.8 times the nominal
current* is flowing in the case of all overload conditions
that lead to a shutdown (regardless of the power supply
and load circuit resistance). The shutdown time ranges
from 100 ms to 3 s depending on the multiple of the
nominal current, or in the event of a short circuit (IK).
Without the current limitation function used at, typically,
1.8 x IN*, a considerably higher overcurrent would flow
in the event of an overload or a short circuit.
Current limitation typically 1.8 x IN where IN =
0.5 A ... 6 A
Current limitation typically 1.5 x IN where IN = 8 A or 10 A
Current limitation typically 1.3 x IN where IN = 12 A

Shutdown current Ishut = 3 A x 1.25 A = 3.75 A
Max. current resistance Rmax = UB/Ishut - 0.050 Ω (internal resistance of miniature circuit-breakers)
Rmax = (19.2 V/3.75 A) - 0.050 Ω = 5.07 Ω
The value calculated, 5.07 Ω, falls between 200 m and 225 m in the table (4.75 Ω and 5.34 Ω).
This means that you can bridge 200 m comfortably.
