The Siemens SENTRON 3VA2010-5HL36-0DC0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to the enclosure's thermal limit.
Breaking capacity — what the voltages tell you
This MCCB delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. That steep drop above 500 V means the 690 V rating is essentially a switching-only figure — don't count on it for high-fault clearing at that voltage. For most 400 V-class industrial panels in North America (480Y/277 V) or Europe (400 V), the 121 kA figure gives solid headroom for high-capacity transformer feeds.
Integrated auxiliaries and release
Factory-fitted with two auxiliary switches (HQ type) and an undervoltage release (UVR).
Power dissipation maxes out at 16 W, so in a sealed enclosure with multiple breakers side-by-side, factor that into the internal temperature rise calculation.
