Breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V, dropping to 7.5 kA at 500 V and 690 V. If your panel runs hotter — say, 65 °C — the same breaker is good for 46 A. The 75.6 kA interrupting rating at 240 V is what the breaker can safely clear under a fault; at 415 V that drops to 52.5 kA, and at 690 V to 7.5 kA. ## Deployment context The undervoltage release (UVR) is factory-fitted, so no field assembly needed.","metaTitle":"3VA1050-3ED36-0DC0 SENTRON MCCB, 50 A, 3-Pole, Line Protecti","metaDescription":"Siemens SENTRON 3VA1050-3ED36-0DC0 molded case circuit breaker, 50 A continuous at 40 °C, 3-pole, line protection.
