What this MCCB is and what it does
The Siemens 3VA2010-6HN36-0HH0 is a SENTRON 3VA2 molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C up to 70 °C — no derating needed in a warm panel. It is a 3-pole unit designed for line protection, meaning it sits at the feeder or branch to protect cables and busbars from overload and short-circuit, not motor or generator protection. Breaking capacity is the headline number here: 242 kA at 240 V AC, 187 kA at 415 V, and still 121 kA at 500 V. That puts it in the high-interrupting category — it clears a fault without the arc re-striking, and it gives you selectivity headroom downstream. At 690 V it drops to 3 kA, so if you are on a 690 V system this is not the breaker for that bus. The breaker ships with a shunt trip release (STL) for remote tripping and a 2-auxiliary-switch plus 1-trip-alarm-switch HQ configuration. No undervoltage release, no ground-fault monitoring, no communication module — this is a straight line-protection MCCB with remote-trip capability and status feedback.
Panel fit and integration notes
Dimensions: 181 mm high, 105 mm wide, 86 mm deep. That 105 mm width is the standard 4-pole-module footprint for a 3-pole MCCB in this class — it occupies three 35 mm DIN-rail spaces plus a bit for the case. The 86 mm depth means it clears most 200 mm deep enclosures with room for wiring gutters. Power loss is 13.5 W maximum. Account for it in the thermal budget. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. The 100 A rating holds flat across the entire operating range — no derating curve to worry about for standard industrial environments.
