This electronic device circuit breaker from Phoenix Contact, part number 2905809, is designed for 24V DC systems and offers a nominal current of 4A. It features active current limitation, ensuring precise protection even with capacitive loads, and an inverted status output for remote monitoring.
The compact design utilizes a plug-in housing concept for modular expansion. The device operates within an ambient temperature range of -25°C to 50°C and has a degree of protection of IP30 at the actuation area. Mounting is done on a base element.
Key electrical specifications include a rated surge voltage of 0.5 kV, a rated insulation voltage of 30V DC for the load circuit, and a voltage drop of 100mV at nominal current. The shutdown time is 100ms, and 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.
Compliance includes UL 2367 and UL 508 standards, as well as EMC standards EN 61000-6-3 for noise emission and EN 61000-6-2 for noise immunity. The flammability rating is V0 according to UL 94.
