The Phoenix Contact 0903040 is an electronic miniature circuit breaker designed for selective protection of 24V DC load circuits. It features a solid-state breaker type with a 500mA nominal current rating and a 24V DC voltage rating.
This circuit breaker provides active electronic current limitation for short circuits and an overload shutdown function starting from 1.1 times the nominal current. It can handle capacitive loads up to 20,000 µF, ensuring reliable operation. The device interrupts current flow in faulty circuits and can be reactivated manually via a slide switch or electronically.
Designed for easy integration, the 0903040 mounts onto NS 35 DIN rails and uses screw connections. It has a design width of 12.5 mm. Signaling of operating and fault states is provided by a multi-color LED and an integrated status output. Wiring tasks can be simplified using power rails and plug-in bridges.
