The 125 A rating holds across 40 °C to 50 °C ambient without derating, then drops only to 122 A at 55 °C and 114 A at 70 °C — that thermal stability matters when the breaker sits in a crowded enclosure near other heat sources. The TM220 release is a fixed thermal-magnetic type, so there is no electronic adjustment; you set the thermal pickup by the breaker's own calibrated bimetal, and the magnetic short-circuit pickup is fixed at the factory. For selectivity studies, the 220 kA at 240 V SCCR gives you headroom to coordinate with downstream breakers without oversizing the main. The breaker measures 101.6 mm wide, 130 mm tall, and 70 mm deep — a standard 4-pole MCCB footprint that fits most DIN-rail or screw-mounted panel layouts. The 4-pole design with 50% N-conductor protection means the neutral pole is rated at half the phase current, which is typical for distribution panels where the neutral carries only unbalanced load. Mounting and busbar connections follow the standard 3VA pattern; no special adapters needed for a SENTRON distribution board.","metaTitle":"Siemens 3VA1112-6FE46-0AA0 SENTRON MCCB, 4-Pole, 125 A, TM22","metaDescription":"Siemens 3VA1112-6FE46-0AA0 SENTRON molded case circuit breaker. 4-pole, 125 A rated continuous current, TM220 release.
