The Siemens SENTRON 3VA2010-5HL32-0AG0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, designed for line protection in distribution panels and industrial switchgear. Its breaking capacity scales with system voltage: 187 kA at 240 VAC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — giving the specifying engineer headroom for high-fault installations without cascading upstream.
The breaker measures 105 mm wide, 181 mm high, and 86 mm deep — sized for standard panel cutouts and DIN-rail or screw-mount integration in a distribution board or motor control center. Power loss is 13.5 W maximum at rated load, which should be factored into enclosure thermal calculations for derating. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
