The Phoenix Contact 2800923 is a single-position electronic device circuit breaker designed for 24V DC systems. It features active current limitation, providing precise nominal current levels and protection even when switching capacitive loads. This modular unit is designed for easy integration with a plug-in housing concept and offers a sophisticated remote signaling capability for monitoring from any location. The control input can be switched via remote control, and supply/remote signaling can be bridged using CLIPLINE complete accessories.
Key technical specifications include an operating voltage range of 18V DC to 30V DC, a nominal current of 2A, and a tripping method classified as 'E (electronic)'. The device has a voltage drop of 100mV at nominal current and a surge voltage rating of 0.5 kV. It operates within an ambient temperature range of 0°C to 50°C and has a degree of protection of IP30. The circuit breaker meets various electrical safety standards, including UL 2367, UL 508, and CSA 22.2 No. 14, as well as EMV standards EN 61000-6-3 and EN 61000-6-2.
Installation instructions note that when mounted in rows without convection cooling, the nominal device current should be limited to 80% due to thermal effects during continuous operation. Special precautions are necessary to prevent component restarts in systems or machines. Parallel connection of multiple circuit breakers is not permitted. The dimensions of the device are 45mm height, 12.3mm width, and 52mm depth.
The nominal operating voltage is 24 V DC, with a range of 18 V DC to 30 V DC.
Operating temperature is 0 °C to 50 °C; storage and transport range is -20 °C to 70 °C.
Nominal current is 2 A.
Electronic (E) tripping method is used.
The module measures 45 mm height, 12.3 mm width, and 52 mm depth. Complete module dimensions are 90 mm x 12.3 mm x 77.3 mm.
