What this MCCB carries — and what it doesn't
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 hits 242 kA at 240 V and 187 kA at 415 V, so it handles high-fault utility feeds without cascading upstream. The built-in undervoltage release (UVR) and two HQ auxiliary switches mean it's wired for remote trip signaling and status feedback out of the box; no add-on module required for basic monitoring.
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. At 415 V it still holds 187 kA, and at 500 V it's 121 kA. 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. The 86 mm depth leaves room for rear bus connections in shallow cabinets. Two HQ auxiliary switches and the undervoltage release are factory-integrated, so no field wiring of separate modules. Power loss is 16 W max — negligible for thermal budgeting in a typical distribution panel.
