The Siemens SENTRON 3VM1192-5MG32-0AA0 is a 3-pole molded case circuit breaker with a TM110M thermal-magnetic overcurrent release, rated 12.5 A continuous at 40 °C and delivering 187 kA interrupting capacity at 240 V AC — enough to handle high-fault utility feeds or transformer secondaries without cascading upstream breakers.
Integration and physical fit
The 76.2 mm width and 70 mm depth fit a standard 3-pole MCCB footprint on a DIN rail or panel-mount base. IP40 on the front means it is protected against solid objects over 1 mm but not sealed against moisture — keep it inside a rated enclosure for washdown or outdoor duty. The TM110M release has an adjustable li max of 200 A (the magnetic trip threshold), and the breaker accepts an optional motor drive for remote operation.
