At 240 V the 220 kA figure covers most utility-side fault levels without requiring a current-limiting upstream device. Thermal derating is minimal through 50 °C (full 125 A), then drops to 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. In a sealed, uncooled enclosure at 55 °C ambient, the usable current is 122 A — a 2.4 % reduction that rarely forces a frame upsizing. Footprint is 101.6 mm wide by 130 mm tall by 70 mm deep — a 4-inch wide body that fits standard MCCB panel cutouts. The 4-pole width matches the common 4-inch module spacing for three-phase-plus-neutral distribution. Maximum power loss is 28.1 W at rated current. In a multi-breaker panel, that heat must be factored into the enclosure's thermal budget — a 10-breaker lineup adds roughly 280 W of internal dissipation. It supports an optional motor drive for remote operation. The 100 % N-conductor protection design means the neutral pole is fully rated, not reduced — critical for four-wire distribution where neutral loading is continuous.","metaTitle":"Siemens 3VA1112-6GE42-0AA0 SENTRON MCCB, 125 A, 4-Pole, 220","metaDescription":"Siemens 3VA1112-6GE42-0AA0 SENTRON molded case circuit breaker, 125 A, 4-pole, TM220 release.
