No undervoltage release, no ground fault monitoring, and no communication function are fitted on this variant. The 50 A rating holds flat from 40 °C through 50 °C ambient, then steps down: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. That 5 A drop from 50 °C to 70 °C is modest — the TM240 release runs cool enough that a panel hitting 60 °C ambient still delivers 47 A continuous. The 3VA frame measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard MCCB footprint that fits most DIN-rail or panel-mount enclosures without oversizing the backpan. Front-face protection is IP40, so it's suitable for general-purpose indoor panels but not washdown environments. The 15,000-cycle mechanical endurance is typical for this class; expect it in a panel that sees occasional switching rather than daily motor-starting duty.","metaTitle":"Siemens 3VA1150-6EF32-0JC0 SENTRON MCCB, 50 A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1150-6EF32-0JC0 molded case circuit breaker, 3-pole, 50 A rated current, TM240 release, shunt trip, 220 kA at 240 V.
