The CLIPLINE series electronic miniature Circuit Breaker selectively protects all 24VDC 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 to 1.8 times the nominal current. This enables capacitive loads of up to 20000µF 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 current circuit can be activated again using the electronic reset input or manually on the device using the slide switch. Wiring and signalling tasks can be implemented easily using power rails and plug-in bridges.

• Selective load protection, electronic shutdown characteristic curve
• Nominal current can be selected in fixed current strengths from 0.5 to 12A
• Safe overload shutdown from 1.1 x IN upward, even with long load lines/small cable cross-sections
• Manual on/off switch (S1)
• Clear signalling by means of LED, SF status output/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 0V, as well as signal rails and signal bridges
