The Siemens SENTRON 3VA2063-5HN32-0AB0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current, with a breaking capacity of 187 kA at 240 VAC. At 415 VAC it still interrupts 121 kA, and at 690 VAC the rating drops to 3 kA, so the voltage-dependent curve governs where you place it in the hierarchy.
Rated insulation voltage is 800 V, which covers 480 V and 600 V class systems with headroom. The 63 A continuous rating holds flat from 40 °C through 70 °C ambient — no derating curve to chase in a warm panel. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C. It carries two auxiliary switches (HP type) for status feedback. The supplied basic switch order code is 3VA20635HN320AA0.
