The interrupting ratings are the headline here: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. The TM240 release is fixed, not adjustable on the long-time or short-time bands — set it and forget it. Above that it starts to step down: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. That's a real derating curve, not a blanket number. The breaker carries IP40 on the front, so it's fine in a clean indoor panel; no washdown rating here. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — standard 3-pole MCCB footprint for a DIN-rail or mounting-plate install.","metaTitle":"Siemens 3VA1150-4EF32-0AB0 SENTRON MCCB, 50 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1150-4EF32-0AB0 molded case circuit breaker, 3-pole, 50 A rated continuous current, 121 kA interrupting at 240 V.
