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. It's designed for line protection, meaning it sits at the feeder or branch to guard against overloads and short circuits, not for motor or generator protection where different trip curves apply.
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). The UVR trips the breaker when control voltage drops below a threshold — standard for emergency-stop circuits or undervoltage protection on motor branches. The HQ aux switches provide status feedback to a PLC or indication lamp without requiring a separate add-on module.
Panel fit and thermal budget
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration. 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. Operates from -25 °C to 70 °C; storage range is -40 °C to 80 °C.
