The Siemens SENTRON 3VA2163-7HN32-0AE0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current at 40 °C through 70 °C — no derating needed across that range, so it holds its full rating in a warm panel. Its interrupting capacity is 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V — high enough for most industrial fault-current scenarios, including large transformer secondaries or motor control centers. Designed for line protection, this MCCB sits in a main distribution panel or feeder circuit where you need a robust overcurrent trip without undervoltage or ground-fault monitoring built in — those are handled externally if required.
At 105 mm wide, 181 mm tall, and 86 mm deep, this breaker fits a standard 3-pole MCCB footprint — check your panel's gutter depth against the 86 mm plus wiring bend radius before committing.
