Breaking capacity reaches 76 kA at 240 V AC and 9 kA at 415 V AC — the 415 V figure governs most industrial panel applications and must be checked against the available fault current at the installation point. ## Thermal derating and continuous current For a panel with internal temperature rise, the 70 °C figure (114 A) is the realistic continuous rating — size upstream conductors and busbars accordingly. At 25.4 mm wide (1 inch), 130 mm tall, and 70 mm deep, this single-pole breaker occupies one standard MCCB mounting slot. ## Electrical ratings and approvals context Rated insulation voltage 500 V, maximum operating voltage 415 V AC / 125 V DC. Maximum power loss 8 W at rated current, relevant for panel thermal calculations.","metaTitle":"Siemens 3VM1112-4ED12-0AA0 SENTRON MCCB, 125 A, 1-Pole, 76 k","metaDescription":"Siemens 3VM1112-4ED12-0AA0 SENTRON molded case circuit breaker, 1-pole, 125 A rated at 40 °C, 76 kA breaking at 240 V, 9 kA at 415 V.
