The Siemens SENTRON 3VA2163-8HK36-0AA0 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, which simplifies panel sizing in warm enclosures. Breaking capacity is rated 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — these are the maximum fault currents the breaker can safely interrupt at each voltage level, giving you the SCCR headroom for high-fault installations.
The 3VA2 frame accepts optional motor drive (listed as an optional extension), which can be specified for remote trip or reclose applications.
