Rating and fit for line protection
The Siemens SENTRON 3VA2063-6HN32-0AC0 is a 3-pole molded case circuit breaker rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its maximum breaking capacity reaches 242 kA at 240 V, stepping down to 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V.
Integration and auxiliary wiring
The breaker ships with two HQ auxiliary switches integrated, so you get status feedback without adding an external accessory block.
