The Siemens 3VA2010-6HL32-0DC0 is a SENTRON 3-pole molded case circuit breaker rated for 100 A continuous at 40 °C through 70 °C — no derating needed across that band, which simplifies panel thermal budgeting.
Interrupting capacity — the real headroom
At 240 V this breaker clears 242 kA — that's utility-transformer-level fault current, typical for a main service disconnect. The drop to 3 kA at 690 V tells you this is a 600 V-class frame; don't spec it for 690 V line protection unless the available fault current is known to be under 3 kA. The 100 A continuous rating is flat across 40–70 °C, which is unusual — most MCCBs start derating above 40 °C. That means you can load it to 100 A in a warm enclosure without recalculating.
Panel fit — dimensions and wiring
The 3VA2010-6HL32-0DC0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling. Two HQ auxiliary switches and the undervoltage release are factory-integrated, so no field wiring of separate modules.
