0903030 Description

Short technical summary and product information.

The Phoenix Contact 0903030 is an electronic miniature circuit-breaker from the CLIPLINE EC-E... series, designed to selectively protect 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 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 for inrush currents without tripping. It offers a nominal current range selectable from 0.5 A to 12 A, with this specific model rated at 10A. The device has a manual on/off slide switch and provides clear signaling via an LED and status output. It has a design width of 12.5 mm and is designed for easy mounting onto NS 35 DIN rails using screw connections.

 

Wiring and signaling tasks are simplified through power rails and plug-in bridges. The electronic reset input is an optional feature. The circuit-breaker is adapted to the nominal current with an integrated fail-safe element. It is suitable for applications requiring precise and fast protection of DC load circuits against overloads and short circuits.
