Interrupting capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 3.4 kA at 690 V. Thermal derating is minimal up to 50 °C (full 63 A), then drops to 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, and 53.6 A at 70 °C. ## Auxiliary releases and switch complement That gives four signal paths for the PLC: breaker open/closed, trip event, and a separate electrical alarm. Mechanical endurance is rated at 20,000 operations — typical for a 63 A MCCB frame used in distribution rather than frequent motor switching. For higher-cycle applications (conveyor start/stop), consider a contactor downstream. Dimensions are 181 mm height, 105 mm width, 86 mm depth.","metaTitle":"Siemens 3VA2063-5KP32-0CL0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA2063-5KP32-0CL0 molded case circuit breaker, 63 A rated, 3-pole, ETU850 electronic trip unit, 187 kA interrupting at 240 V.
