The 2800843 is a single-position thermomagnetic device circuit breaker designed for overcurrent protection in DC systems. It operates with a nominal current of 10 A and a rated voltage of 50 V DC, featuring a fast-blow (SFB) tripping characteristic ideal for protecting long cable paths. This device utilizes a thermomagnetic trip mechanism and includes a single PDT contact for remote status signaling. Housed in a compact 12.3 mm wide plug-in module, it is rated for an operating ambient temperature range of -30 °C to 60 °C. Its modular, plug-in design for a base element facilitates easy installation and system expansion in industrial control and automation applications.
