The Siemens SENTRON 3VA2110-5HL32-0AC0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C through 70 °C — no derating needed across that band, which simplifies panel schedules in warm enclosures. Its 187 kA breaking capacity at 240 V drops to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and 3.7 kA at 690 V — so the SCCR you design for depends entirely on the system voltage. At typical 480 V distribution, you still have 75.6 kA of interrupting capacity, which covers most industrial service-entrance and feeder applications.
Integration into the switchboard
Power loss is rated at 10 W maximum, which keeps internal cabinet temperature rise manageable even in densely packed distribution boards.
