That means on a 415 V distribution board with a high-fault transformer, it handles the worst-case bolted fault without the breaker welding open — the interrupting rating is the number that keeps the arc flash boundary in check, not the continuous amps. ## Integrated undervoltage release That UVR means if the control voltage dips below the dropout threshold, the breaker trips — a common requirement on conveyor systems or pump stations where a lost phase or sagging supply needs to drop the load before the motor contactor tries to reaccelerate into a stalled rotor. No separate shunt-trip module to buy and wire; it's inside the breaker. ## Panel fit and thermal management At 70 mm deep, 76.2 mm wide, and 130 mm tall, this breaker fits a standard 3-pole MCCB footprint on a DIN rail or mounting plate. The maximum power loss is 19.8 W — that's the heat it dumps into the enclosure at full rated load. In a sealed stainless panel with no fan, that 20 W per breaker adds up fast; plan the thermal rise against the 70 °C max operating ambient and the 80 °C storage limit.","metaTitle":"Siemens 3VA1063-2ED36-0CC0 SENTRON MCCB, 63 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1063-2ED36-0CC0 molded case circuit breaker, 63 A rated at 40 °C, 3-pole, 52.5 kA at 240 V.
