At 415 V it still interrupts 154 kA, dropping to 121 kA at 440 V, and 17 kA at 500 V and 690 V respectively, giving you selectivity headroom across common industrial voltages. ## Thermal derating and real-world loading At 55 °C it drops to 49 A, then 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. If your panel runs hot near other heat sources, you still get 45 A at the upper operating limit. The max power loss is 14.6 W, manageable for a DIN-rail enclosure without forced cooling. The 3-pole design with 4 auxiliary switches (HQ type) gives you plenty of status feedback for PLC or HMI inputs. Insulation voltage rated at 800 V, operating range from -25 °C to 70 °C, storage from -40 °C to 80 °C.","metaTitle":"Siemens 3VA1150-6EF32-0AE0 SENTRON MCCB, 50 A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1150-6EF32-0AE0 molded case circuit breaker, 3-pole, 50 A continuous, TM240 thermal-magnetic release, 220 kA interrupting at 240 V.
