The Siemens SENTRON 3VA2110-6HN32-0AH0 is a 3-pole molded case circuit breaker rated for 100 A continuous current with a flat thermal derating curve — it holds 100 A from 40 °C all the way up to 70 °C, so no knock-down in a hot panel. Breaking capacity is tiered by system voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. The 86 mm depth x 105 mm width x 181 mm height footprint fits standard SENTRON panel cutouts — no surprises on the DIN or mounting plate.
Auxiliary switch complement
That gives you two independent status signals (open/closed) and a dedicated trip-indication contact for remote annunciation or PLC input. No field-add kit needed for basic signaling.
