The 3VA2010-5HN36-0BC0: Breaking capacity is the headline here: 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 187 kA figure at 240 V means it handles high-fault utility feeds without cascading upstream — critical for service-entrance or main-tie applications where available fault current is high. Rated current holds flat at 100 A across the full ambient temperature range from 40 °C to 70 °C — no derating needed in a warm enclosure, which simplifies panel design.
Dimensions are 181 mm high, 105 mm wide, 86 mm deep — standard MCCB footprint for a 100 A frame. Fits a typical 3-pole slot in a SENTRON distribution panel or any DIN-rail-mount enclosure with the appropriate adapter plate. Comes with an undervoltage release (UVR) and two auxiliary switches (HQ design) factory-fitted. The UVR trips the breaker when control voltage drops, which is standard for emergency-stop circuits or undervoltage protection on motor feeds. The auxiliary switches provide status feedback to a PLC or indicator lamp. Power loss is 16 W maximum at rated load — modest for a 100 A frame, but worth accounting for in a densely packed enclosure to stay within the thermal budget.
Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. The storage minimum is the more restrictive limit for warehousing — keep it above -40 °C to avoid seal or mechanism issues.
