The SENTRON 3VA2163-6HL32-0HH0 is a 3-pole molded case circuit breaker rated for 63 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. Breaking capacity hits 242 kA at 240 V, 187 kA at 415/440 V, and 121 kA at 500 V; at 690 V it drops to 3.7 kA, so keep that in mind for higher-voltage taps.
Line protection with shunt trip
It's a straightforward line-side breaker with a remote-trip coil and auxiliary contacts for basic indication.
Panel fit
That depth is the key clearance number for enclosure depth — 86 mm (3.39 in) means it fits most standard 200 mm deep panels with room for wiring gutters.
