The TM240 thermal-magnetic release provides fixed overload pickup and instantaneous magnetic trip, factory-set for distribution feeder applications. Short-circuit performance is voltage-dependent: 220 kA at 240 V AC, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V. That 220 kA figure at 240 V places it in the high-interrupting category for North American 240/120 V distribution panels; the 17 kA at 690 V still covers most European industrial feeders. ## Built-in auxiliary and alarm switching Factory-fitted with one auxiliary switch and one trip-alarm switch (HQ type), so the breaker reports its open/closed state and whether it tripped on fault — no separate accessory block to order and install. The auxiliary switch shares the same internal mechanism as the base switch 3VA11506EF360AA0, ensuring contact alignment. Dimensions: 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that fits most Siemens SENTRON mounting plates and third-party DIN-rail adapters. Maximum power loss 14.6 W, which matters for enclosure thermal calculations when multiple breakers are ganged. Trip indicator is present, so a quick visual scan of the panel shows which breaker cleared the fault.","metaTitle":"Siemens 3VA1150-6EF36-0AF0 SENTRON MCCB, 50 A, 3-Pole, 220 k","metaDescription":"Siemens SENTRON 3VA1150-6EF36-0AF0 molded case circuit breaker, 50 A rated at 40 °C, 3-pole, breaking capacity up to 220 kA at 240 V.
