The Siemens SENTRON 3VA2110-6HL32-0JH0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed as the panel warms up.
The breaker includes a shunt trip release and two auxiliary switches plus a trip alarm switch, giving you remote trip and status feedback without an add-on module. Power loss is capped at 10 W, so thermal management inside a crowded enclosure stays manageable.
