Breaking capacity runs 76 kA at 240 V AC, dropping to 53 kA at 415 V, 32 kA at 440 V, and 12 kA at 500 V — match the available fault current at your service voltage to confirm adequate SCCR headroom. The 125 A rating holds flat to 50 °C; 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. Dimensions are 101.6 mm wide, 130 mm tall, and 70 mm deep — a 4-pole MCCB that fits standard distribution panel gutters.","metaTitle":"SENTRON 3VM1112-3ED42-0AA0 4-Pole MCCB, 125 A, 76 kA at 240","metaDescription":"SENTRON 3VM1112-3ED42-0AA0 molded case circuit breaker, 4-pole, 125 A continuous, TM210 release.
