At 240 V it interrupts 220 kA, dropping to 17 kA at 690 V; the breaking capacity at your system voltage determines whether this breaker clears a fault without cascading upstream. The 70 mm depth and 76.2 mm width fit standard MCCB panel cutouts, and the 130 mm height leaves room for the undervoltage release (UVR) module and two auxiliary switches HQ. With two auxiliary switches HQ, the panel gets status feedback without adding external relays. ## Thermal derating and enclosure integration The 50 A rating holds from 40 °C to 50 °C, then derates to 49 A at 55 °C and 45 A at 70 °C. The insulation voltage of 800 V covers 480 V and 600 V class systems with margin.","metaTitle":"Siemens SENTRON 3VA1150-6EF32-0DC0 MCCB, 50 A, 220 kA","metaDescription":"Siemens SENTRON 3VA1150-6EF32-0DC0 molded case circuit breaker, 3-pole, 50 A at 40 °C, 220 kA at 240 V, undervoltage release, current lifecycle.
