The Siemens SENTRON 3VA2110-6HL32-0AD0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range of 40 °C to 70 °C — no derating needed up to that ceiling. The adjustable overload trip covers 150 A to 1200 A, which means it can protect a feeder or a large motor branch where the load is well above the breaker's own frame rating. Short-circuit current ratings climb to 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 — so it handles high-fault utility feeds without cascading upstream.
The basic switch assembly is order code 3VA21106HL320AA0.
