The Siemens 3VA2110-6HN36-0KL0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current on a 1200 A frame, configured as a 3-pole device for line protection. Its interrupting capacity reaches 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V — figures that tell you it can clear high-fault currents without cascading upstream, which matters for selectivity studies in industrial switchboards. The 100 A rating holds flat across the full ambient temperature range from 40 °C to 70 °C, so no derating curve to chase in a warm enclosure. Power loss is a modest 10 W maximum, which keeps internal heat rise manageable in a dense panel.
Auxiliaries and integration
That gives you both status feedback and alarm annunciation without adding external relay logic. Dimensions are 181 mm high, 105 mm wide, and 86 mm deep — a standard 3-pole MCCB footprint that fits Siemens SENTRON mounting bases and most DIN-rail adapter plates. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
