The Siemens SENTRON 3VA2010-5HN32-0JC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its 187 kA interrupting capacity at 240 V AC handles high-fault utility feeds; at 415/440 V it still breaks 121 kA, dropping to 75.6 kA at 500 V and 3 kA at 690 V.

Breaking Capacity & Selectivity
At 690 V the 3 kA rating limits it to low-fault applications; for high-voltage motor circuits you'd step to a larger frame.
