The Phoenix Contact 3000757 is a solid-state electronic circuit breaker designed for selective protection of 12V DC load circuits. It features active electronic current limitation for short circuits and overload shutdown, reacting quickly to over-current conditions. The current limitation restricts fault current to 1.5 to 1.8 times the nominal current rating, preventing potential DC output voltage loss from power supply self-protection.
This circuit breaker can protect capacitive loads up to 75,000 µF. It has a 4A nominal current rating and operates at 12V DC. Local status indication is provided by a multi-color LED, and remote status indication is available via a status output. Manual on/off and reset functions are managed by an integrated slide switch.
Designed for easy installation, the EC 1 12DC... series can be snapped onto 35 mm mounting rails (EN 50022). It has a narrow width of 12.5 mm, minimizing space requirements on the rail. Screw connection technology ensures secure wire connections. The integrated current distribution system allows for easy wiring using available busbars.
