The Phoenix Contact 0903045 is an electronic miniature circuit-breaker from the CLIPLINE EC-E series, designed for selective protection of 24V DC load circuits. It features active electronic current limitation for short circuits and an overload shutdown function starting from 1.1 times the nominal current (IN). This design ensures faster reaction to overloads than the power supply unit, with residual current restricted to 1.3 - 1.8 times the nominal current.
This circuit-breaker supports capacitive loads up to 20,000 µF, allowing them to be switched on without tripping unless an overload or short circuit occurs. Once a fault is detected, the load output is blocked, and current flow is interrupted. The device can be reactivated manually via a slide switch or through an electronic reset input. It has a nominal current rating of 4A and a voltage rating of 24V DC.
Designed for modular installation, the EC-E... series circuit-breaker has a width of 12.5 mm and can be snapped onto NS 35 DIN rails using screw connections. It provides clear signaling of operating and fault states via a multi-color LED and an integrated status output. Wiring tasks are simplified using power rails and plug-in bridges.
