That interrupting rating drops to 52.5 kA at 415 V and 32 kA at 440 V, so the voltage you're clearing against matters — at 690 V it's still rated for 10.5 kA, which covers most industrial motor branch circuits on that voltage class. The TM240 thermal-magnetic release handles the overload and short-circuit curve; no electronic trip unit here, so coordination studies stay simple. Thermal derating is flat from 40 °C to 50 °C at 50 A, then drops to 48 A at 55 °C and 45 A at 70 °C. The 3VA1150-3EF32-0HC0 measures 70 mm deep by 76.2 mm wide by 130 mm high. Front protection is IP40, which is typical for a panel-mounted breaker; no washdown rating, so keep it behind the gland plate. The auxiliary release order code for the integrated shunt trip is 3VA9688-0BL30 if you need a spare or replacement module. Latching endurance is rated at 15,000 operations — that's the mechanical life for the switching mechanism.","metaTitle":"Siemens 3VA1150-3EF32-0HC0 SENTRON MCCB, 50 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1150-3EF32-0HC0 molded case circuit breaker, 50 A rated continuous current, 3-pole, 75.6 kA at 240 V.
