The interrupting ratings are what matter for panel coordination: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Dimensions: 130 mm height, 76.2 mm width (3 in), 70 mm depth (2.76 in). Standard 3-pole MCCB footprint for panel mounting on a backplate or DIN rail adapter. The TM240 release is factory-set; no undervoltage release or shunt trip fitted on this variant (no voltage trigger, no communication module). The 50 A continuous rating is the thermal current (Ith) at 40 °C ambient; the breaker carries the same 50 A up to 50 °C, then derates linearly to 45 A at 70 °C.","metaTitle":"Siemens 3VA1150-4EF32-0AG0 SENTRON MCCB, 50A, 121kA at 240V","metaDescription":"Siemens 3VA1150-4EF32-0AG0 SENTRON molded case circuit breaker, 3-pole, 50A rated at 40°C, 121kA breaking capacity at 240V.
