The TM240 release means the thermal pickup is fixed; you get a single time-band adjustment (tr max. 1 s) on the magnetic trip, not a full electronic curve. The 100 A rating holds from 40 °C through 50 °C ambient; above that it steps down — 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, 90 A at 70 °C. Width is 76.2 mm, depth 70 mm, height 130 mm — a standard 3-pole MCCB footprint that drops into a SENTRON distribution board or a separate enclosure. ## What the auxiliary contact version gives you This variant ships with 2 auxiliary switches (HQ type) built in. That means you get two form-C contacts for status feedback — one to signal the breaker's open/closed state to a PLC or indicator lamp, the other for a remote trip alarm. No separate add-on module needed.","metaTitle":"Siemens 3VA1110-5EF32-0AC0 SENTRON MCCB, 100 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA1110-5EF32-0AC0 molded case circuit breaker, 100 A rated continuous current, 187 kA interrupting at 240 V.
