Interrupting capacity varies with line voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. ## Auxiliaries and releases fitted from the factory The UVR means the breaker trips on loss of control voltage; if your safety circuit expects a shunt trip or you need a separate undervoltage coil, this has it built in. Mechanical endurance is rated at 15 000 cycles — typical for a 125 A frame in distribution duty; not a high-cycling motor-switching MCCB, but fine for infrequent manual or remote switching in a feeder panel. ## Panel fit and footprint Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole SENTRON 3VA frame that drops into existing DIN-rail or screw-mount panel layouts without re-drilling.","metaTitle":"Siemens 3VA1112-3EF32-0CC0 SENTRON MCCB, 125 A, 75.6 kA at 2","metaDescription":"Siemens SENTRON 3VA1112-3EF32-0CC0 molded case circuit breaker, 125 A rated, TM240 trip, 75.6 kA at 240 V.
