This breaker delivers 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 690 V. At 240 V it handles virtually any utility fault; at 415 V it still clears 154 kA, which covers most industrial secondary substations. ## Thermal derating — when the 50 A rating holds and when it doesn't At 55 °C it derates to 48 A, at 60 °C to 47 A, at 65 °C to 46 A, and at 70 °C to 45 A. The undervoltage release (UVR) is the 3VA9608-0BB25 auxiliary trip; if you're replacing an older unit, confirm the UVR coil voltage matches your control circuit.","metaTitle":"Siemens 3VA1150-6EF36-0DA0 SENTRON MCCB, 50 A, 220 kA at 240","metaDescription":"Siemens SENTRON 3VA1150-6EF36-0DA0 molded case circuit breaker, 50 A rated, 220 kA breaking at 240 V.
