Interrupting capacity is 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V, so it handles high-fault scenarios common in industrial switchboards without cascading upstream. At 70 mm deep, 76.2 mm wide, and 130 mm tall, the breaker fits standard SENTRON 3VA panel cutouts and leaves room for side-by-side mounting in a distribution board.","metaTitle":"Siemens 3VA1112-5EF32-0CC0 SENTRON MCCB, 125 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1112-5EF32-0CC0 molded case circuit breaker, 125 A, 3-pole, interrupting capacity 187 kA at 240 V AC.
