The Siemens SENTRON 3VA2110-6HL32-0AF0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, designed for line protection in distribution panels and industrial switchgear. Its breaking capacity reaches 242 kA at 240 VAC, 187 kA at 415 VAC and 440 VAC, 121 kA at 500 VAC, and 3.7 kA at 690 VAC — figures that give the specifying engineer substantial SCCR headroom for high-fault installations without cascading upstream.
Dimensions are 181 mm high, 105 mm wide, and 86 mm deep — a standard MCCB footprint that fits most DIN-rail or panel-mount enclosures without rework. Power loss is 10 W maximum at rated current, a figure to include in enclosure thermal calculations when grouping multiple breakers.
Ratings & Derating
The 100 A continuous rating holds flat across the full ambient temperature range from 40 °C to 70 °C — no derating required up to the maximum operating temperature of 70 °C. Adjustable thermal-magnetic trip unit covers 150 A to 1 200 A, so the breaker can be tuned to protect downstream conductors or loads within that window. Storage range spans -40 °C to 80 °C; operating range is -25 °C to 70 °C.
