It's built for motor protection with phase failure detection built in, so if you lose a leg on a pump or conveyor, this breaker trips and keeps the windings from cooking. Breaking capacity is serious: 187 kA at 240 V, 121 kA at 415 V, and still 75.6 kA at 500 V. That kind of headroom means it'll clear a fault on a big motor starter or a feeder without welding the contacts shut — even on a stiff industrial grid. The shunt trip (STL) release and the auxiliary switch block (2 aux + 1 trip alarm + 1 electrical alarm) are factory-installed, so no field wiring of add-on kits. Power loss is capped at 10 W max, which keeps the heat out of a tightly packed enclosure.","metaTitle":"Siemens 3VA2110-5MN32-0KL0 SENTRON MCCB, 100 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2110-5MN32-0KL0 molded case circuit breaker, 100 A rated, 3-pole, breaking capacity 187 kA at 240 V.
