The 2800844 is a single-position, plug-in thermomagnetic device circuit breaker designed for overcurrent protection. It has a nominal current rating of 12 A and can operate at voltages up to 240V AC or 50V DC. This device features a thermomagnetic trip mechanism with a fast-acting SFB (Selective Fuse Breaking) characteristic, providing reliable protection. It includes one PDT auxiliary contact for remote status signaling and is designed as a plug for a compatible base element. Its compact, modular design and SFB tripping characteristic make it ideal for providing maximum overcurrent protection across long cable paths in industrial control systems.
