What this 3VA2010-5JQ32-0DL0 is and what it does
The Siemens 3VA2010-5JQ32-0DL0 is a SENTRON molded case circuit breaker (MCCB) designed for line protection in 3-phase distribution panels. It's rated for a continuous 100 A at 40 °C — and holds that same 100 A all the way up to 70 °C, which means no derating headache in a warm enclosure. Three poles, so it handles three-phase loads without needing a fourth pole for the neutral. Breaking capacity is where this breaker earns its keep: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and still 3 kA at 690 V. That's a high-interrupting rating for a 100 A frame — it'll clear a bolted fault upstream without the arc flash climbing into the next panel. The 187 kA at 240 V figure is the standout; you'd typically see that on a larger-frame breaker.
What the auxiliary package means for panel wiring
Includes two auxiliary switches, one trip alarm switch, one electrical alarm switch (HQ), and an undervoltage release. Communication function is present on this variant. It can interface with a higher-level system via the SENTRON communication module.
Physical fit and panel integration
Dimensions: 105 mm wide, 181 mm tall, 86 mm deep. That's a standard 3-pole MCCB footprint for the 100 A frame class — it'll drop into a SENTRON panelboard or a DIN-rail adapter without surprises. The 86 mm depth is shallow enough for a 200 mm deep enclosure with room for wiring gutters. Power loss is 16 W maximum at rated current, so factor that into enclosure thermal calculations if you're packing multiple breakers in a small cabinet.
Temperature performance and storage limits
Operating temperature range is -25 °C to 70 °C, with the full 100 A rating held across that entire span. Storage range is wider: -40 °C to 80 °C, which covers most warehouse and shipping conditions. No special cold-weather start-up sequence needed — the breaker is ready at -25 °C.
