The Phoenix Contact EC 1 12DC/3A S-C is an electronic circuit breaker designed for selective protection of 12V DC load circuits in both hazardous and non-hazardous environments. It features a solid-state breaker type and a current rating of 3A.
This circuit breaker provides active electronic current limitation for short circuits, restricting fault current to 1.5 to 1.8 times the nominal current rating. This prevents the loss of DC output voltage that can occur when a fault triggers a power supply into self-protection mode. It can protect capacitive loads up to 75,000 µF.
Installation is facilitated by its ability to snap onto 35 mm mounting rails (EN 50022). With a width of only 12.5 mm, it conserves space on the rail. Secure and reliable wire connections are ensured by screw connection technology. The integrated current distribution system allows for easy wiring using available busbars.
Features include manual on/off and reset via an integrated slide switch. Remote status indication is available via a status output, signaling +12V = OK. A multi-color LED provides local status indication.
