Its breaking capacity hits 121 kA at 240 V AC, 75.6 kA at 415 V, and 52.5 kA at 440 V — numbers that matter when you're coordinating downstream devices and need headroom for fault currents. At 55 °C it drops to 96 A, at 60 °C to 94 A, and at 70 °C to 90 A. That's a gentle slope; you can still push 90 A in a hot cabinet without tripping early. The TM240 release is a fixed thermal-magnetic type — no interchangeable trip units, so the breaker is factory-set for that 100 A frame. At 415 V the 75.6 kA still covers typical utility fault levels in industrial distribution. The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most DIN-rail or panel-mount enclosures without re-drilling. No undervoltage release, no shunt trip beyond the listed STL option — the integrated shunt trip (STL) is present, wired to the auxiliary release terminals.","metaTitle":"Siemens 3VA1110-4EF32-0KC0 SENTRON MCCB, 100 A, 3-Pole, 121","metaDescription":"Siemens SENTRON 3VA1110-4EF32-0KC0 molded case circuit breaker, 100 A rated, 3-pole, 121 kA breaking at 240 V.
