Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V, so it handles high-fault-current scenarios on 480Y/277 V or 400 V industrial services without cascading upstream. Above that, it derates linearly: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. The breaker measures 130 mm high, 101.6 mm wide, and 70 mm deep — a 4-pole footprint that fits standard SENTRON 3VA mounting bases. No undervoltage release or communication module is fitted on this variant, so it's a straight thermal-magnetic unit with no auxiliary wiring. ## Selectivity and Coordination Notes For selectivity studies, the TM240 release gives a fixed thermal pickup at 100 A and a magnetic trip adjustable from 5× to 12× In (500–1200 A).","metaTitle":"Siemens 3VA1110-3EF42-0AA0 SENTRON MCCB, 100 A, 4-Pole, 70 m","metaDescription":"Siemens SENTRON 3VA1110-3EF42-0AA0 molded case circuit breaker, 100 A at 40 °C, 4-pole, TM240 release, 75.6 kA at 240 V.
