The Phoenix Contact 2905808 is a compact, single-pole electronic device circuit breaker. It operates at 24V DC with a nominal current rating of 3A and features active current limitation, typically 1.25 times the nominal current. This breaker is designed for use on a base element and offers an inverted status output and control input.
Key electrical specifications include a rated surge voltage of 0.5 kV and a rated insulation voltage of 30V DC for the load circuit. The voltage drop at nominal current is 100 mV, and the shutdown time for the load circuit is 100 ms. It can handle a maximum capacitive load of 20000 µF. The status output provides a 24V DC signal with a maximum short-circuit-proof current of 0.2A.
Mechanically, the device has dimensions of 45mm height, 12.3mm width, and 52mm depth. It operates within an ambient temperature range of -25°C to 50°C and has a degree of protection of IP30 for the actuation area. The flammability rating is V0 according to UL 94. The circuit breaker complies with standards such as UL 2367 and UL 508, and meets EMC requirements EN 61000-6-3 and EN 61000-6-2.
This electronic device circuit breaker is suitable for applications requiring precise current limitation and reliable signaling. Its modular design allows for expansion, and the sophisticated remote signaling concept enables monitoring from any location. The control input can be switched via remote control, and active current limitation is maintained even when switching capacitive loads.
