What this MCCB carries and where it fits
The Siemens 3VA2010-8KQ36-0AA0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection in distribution panels. It's a 3-pole unit rated for 100 A continuous current at 40 °C through 70 °C — no derating needed across that span, which simplifies panel schedules in warm enclosures. The adjustable thermal-magnetic trip covers 150 A minimum to 1 200 A maximum, so this frame size handles a wide range of downstream loads from a single physical footprint. Breaking capacity is the headline: 440 kA at 240 V AC, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. Those numbers mean it can interrupt fault currents up to utility-grade levels without cascading upstream — critical for high-fault locations like transformer secondaries or large motor control centers. The 800 V rated insulation voltage confirms it's built for 690 V line-to-line systems with margin.
Integration and panel fit
Dimensions are 181 mm high, 105 mm wide, 86 mm deep — a standard SENTRON 3VA2 frame that mounts on DIN rail or direct panel. The 86 mm depth is shallow enough for compact enclosures; the 105 mm width means it occupies three pole spaces on a DIN rail. Communication function and ground-fault monitoring via summation current formation are built in, so you don't need external modules for those features.
