The Siemens SENTRON 3VA2163-6HN32-0HA0 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. Interrupting capacity is 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. The drop to 3.7 kA at 690 V tells you this breaker is sized for 480 V and below applications; at 690 V it's still rated, but the fault capacity is modest. It's a line-protection design (not feeder or motor protection), so the trip curve is fixed for cable and busbar protection. The basic switch inside is order code 3VA2163-6HN32-0AA0.
No trip indicator on the front face, so fault indication relies on the shunt trip or downstream signaling.
