The Siemens SENTRON 3VA2010-6HL32-0KC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current with no derating across the full ambient range from 40 °C to 70 °C — that means it holds its full 100 A rating even in a hot panel or near other heat sources. It's designed for line protection (feeder duty), with an adjustable thermal-magnetic trip unit covering 150 A minimum to 1 200 A maximum — so you set the actual trip point to match the downstream load, not the other way around. Interrupting capacity is 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V — high enough for most industrial service-entrance or distribution panels where fault current is substantial.
Built-in accessories and release options
Power loss is 13.5 W maximum at rated load — useful for thermal budget calculations inside a sealed enclosure.
