The interrupting ratings climb to 187 kA at 240 V AC and stay at 121 kA at 415 V; above 500 V it still clears 17 kA, so this breaker handles high-fault utility feeds without cascading upstream. A built-in shunt trip (STL) release allows remote tripping from a PLC or emergency-stop circuit — no separate undervoltage release is fitted here. At full 63 A load the breaker dissipates 17.3 W maximum — a factor when calculating enclosure ventilation. No trip indicator is fitted on this variant.","metaTitle":"Siemens 3VA1163-5EF32-0JA0 SENTRON MCCB, 63A, 187kA at 240V","metaDescription":"Siemens SENTRON 3VA1163-5EF32-0JA0 molded case circuit breaker, 3-pole, 63A rated at 40°C, 187kA SCCR at 240V AC.
