Rated at 125 A at 40 °C, it handles continuous loads up to that current in a 40 °C ambient, with gradual derating to 114 A at 70 °C. The interrupting ratings are substantial: 76 kA at 240 V, 53 kA at 415 V, 32 kA at 440 V, and 12 kA at 500 V. The rated insulation voltage is 800 V, so it's suitable for 480/277 V and 400/230 V systems with headroom. Front protection is IP40, so it's protected against tools and small wires entering the front but not sealed against dust ingress — standard for panel-mount MCCBs. The 4-pole design allows it to switch all three phases plus neutral in a 3-phase 4-wire system. No undervoltage release, no voltage trip, no communication function, and no ground-fault monitoring — this is a basic thermal-magnetic breaker for straightforward feeder or branch protection. The TM220 release is a fixed thermal-magnetic type; no interchangeable trip units here.","metaTitle":"SENTRON 3VM1112-3EE42-0AA0 Molded Case Circuit Breaker, 125","metaDescription":"SENTRON 3VM1112-3EE42-0AA0 4-pole molded case circuit breaker, 125 A at 40 °C, TM220 release, 76 kA at 240 V.
