The Siemens SENTRON 3VA2010-6KQ36-0AA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current, designed for line protection in distribution panels. It sits at 86 mm deep by 105 mm wide by 181 mm tall — fits a standard 3-pole MCCB footprint on a DIN rail or panel-mount backplate.
Interrupting capacity and what it means on site
This breaker clears 242 kA at 240 V and 187 kA at 415 V — that's a lot of fault current, so it's sized for high-available-fault panels like a main or large feeder. At 690 V it still holds 3 kA, which covers most motor branch circuits. The 100 A rating holds flat from 40 °C to 70 °C, meaning no derating worry in a warm enclosure.
Lifecycle and sourcing
This part is listed as current production — no end-of-life notice. Sourced to order through independent distribution; availability and current pricing confirmed at quote time against an RFQ.
Integration notes for the panel builder
Rated insulation voltage is 800 V, so it's fine on 480/600 V systems. It includes a communication function for remote monitoring or trip indication, plus summation ground-fault monitoring on the L-conductor — useful for selective coordination on a grounded-wye system. Power loss maxes at 13.5 W, so no special ventilation needed in a standard enclosure.
