Breaking capacity is 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V — figures that give solid selectivity headroom in high-fault-current panels. Current rating holds at 125 A up to 50 °C ambient; above that it derates to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. Maximum power loss is 28.1 W. Dimensions are 101.6 mm wide, 130 mm high, 70 mm deep — a 4-pole MCCB that fits standard SENTRON 3VA panel cutouts and busbar systems. Front protection is IP40; the body is designed for screw-mounting in enclosed switchboards.","metaTitle":"Siemens 3VA1112-5GF46-0AA0 SENTRON MCCB, 125 A, 4-Pole, 187","metaDescription":"Siemens SENTRON 3VA1112-5GF46-0AA0 molded case circuit breaker, 125 A, 4-pole, breaking capacity 187 kA at 240 V.

The physical footprint and mounting pattern are the same across the 3VA family, so panel cutouts and busbar positions match. Verify the current rating and trip curve against your load before swapping — the breaker itself will fit the same footprint."},{"question":"What compliance documentation does Siemens provide for 3VA1112-5GF46-0AA0?","answer":"Standard Siemens documentation for the SENTRON 3VA series includes the device manual, CE declaration of conformity, and UL/CSA certification data.
