At 415 V the rating drops to 32 kA, and at 690 V to 7.5 kA. The 50 A thermal rating holds from 40 °C through 50 °C without derating; at 70 °C it still carries 45 A. That thermal stability means you don't have to oversize the frame for warm enclosures. ## Auxiliary switching and shunt trip built in That covers status feedback to a PLC and emergency-stop integration without adding external relay logic. The undervoltage release is not fitted on this order code — if UVR is required, specify the -0KH0 variant with that option.","metaTitle":"3VA1050-2ED36-0KH0 SENTRON MCCB, 50A, 3-Pole, 52.5kA at 240V","metaDescription":"Siemens SENTRON 3VA1050-2ED36-0KH0 molded case circuit breaker, 50A rated at 40°C, 3-pole, 52.5kA breaking capacity at 240V.
