The Siemens SENTRON 3VA2010-6HL32-0HL0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C, with a breaking capacity of 242 kA at 240 V AC — enough to handle high-fault utility feeds or transformer secondaries without cascading upstream.
Above that it derates linearly: 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C. If your panel runs hot — near a drive or transformer — factor the 70 °C ceiling into your load calculation. Maximum power loss is 13.5 W, manageable for standard enclosure thermal budgets.
Short-circuit performance varies with system voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4 kA at 690 V.
