The Phoenix Contact 2800904 is a single-pole, solid-state electronic device circuit breaker designed for 24VDC systems. It offers active current limitation, providing precise nominal current levels and protection even when switching capacitive loads. The breaker features a 1 N/O (normally open) contact for remote signaling of its operating state, enabling monitoring from any location.
With a compact design and modular expansion capabilities through a uniform, plug-in housing concept, this circuit breaker is suitable for various applications. It operates within a voltage range of 18VDC to 30VDC and has a nominal current rating of 4A. The device is mounted on a base element and has dimensions of 45mm height, 12.3mm width, and 52mm depth.
Key technical specifications include a voltage drop of 100mV at nominal current, a switch-off threshold typically at 1.25 times the nominal current, and a closed-circuit current of 8mA when switched on. The auxiliary contact operates with a minimum voltage of 10VDC and a maximum of 30VDC, with a current range from 10mA to 0.5A. The device is protected to IP30 in the actuation area and operates in ambient temperatures from 0°C to 50°C.
Compliance standards include UL 2367, UL 508, CSA 22.2 No. 14, and EMV EN 61. The country of origin is Germany. This circuit breaker is designed for reliable protection and monitoring in electronic systems.
