The interrupting ratings climb to 121 kA at 240 V AC and 75.6 kA at 415 V AC — numbers that tell you this breaker can clear high-fault conditions without cascading upstream, which is the deciding factor for panel SCCR compliance. The TM240 release means the thermal element is calibrated for a 240 A frame — the breaker's continuous rating is set by the installed trip unit, not the frame. That gives you headroom to swap in a higher-rated trip later if the load grows, without pulling the breaker out of the panel. The auxiliary contacts let the PLC or BMS know the breaker state without adding a separate contactor block. 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. The IP40 front protection means it's suited for indoor panel use where no water jets are present; keep it behind a locked door in washdown zones.","metaTitle":"Siemens 3VA1110-4EF32-0JH0 SENTRON MCCB, 100 A, 3-Pole, 121","metaDescription":"Siemens 3VA1110-4EF32-0JH0 SENTRON molded case circuit breaker, 100 A rated, 3-pole, 121 kA at 240 V.
