The Siemens SENTRON 3VA2110-5MN36-0HL0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed as the panel warms up. Interrupting capacity hits 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 — so it handles high-fault scenarios on the low-voltage side of a distribution transformer without cascading upstream.
What the ratings mean in practice
That means you can mount it in a warm panel (say, next to a drive or transformer) without having to oversize the frame. The motor protection design includes phase failure detection, which catches a lost phase before the motor burns out.
