The Siemens SENTRON 3VA2110-5HL36-0DL0 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. That flat thermal curve means it holds its 100 A rating in a warm panel without a size bump. Its interrupting ratings climb to 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
Verify the busbar or lug kit pattern against your existing panel layout; the basic switch variant is 3VA21105HL360AA0.
