The Siemens SENTRON 3VA2110-6HN36-0CA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full operating temperature range from 40 °C to 70 °C — no derating needed up to that ceiling. Its interrupting capacity hits 242 kA at 240 V and still holds 187 kA at 415 V, which gives you serious fault-clearing headroom on a 480 V or 400 V distribution panel without cascading upstream breakers.
Line protection with undervoltage release
This breaker is built for line protection — feeder or main distribution duty — not motor branch-circuit protection. The UVR is factory-fitted, so you avoid the separate aux module and wiring step.
