The Siemens SENTRON 3VA2110-5HN32-0DH0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, designed for line protection in industrial distribution panels.
Rated 100 A continuous from 40 °C through 70 °C ambient — no derating curve to chase across the operating range, which simplifies panel thermal calculations. The 86 mm depth and 105 mm width fit standard MCCB mounting footprints; the 181 mm height leaves room for auxiliary wiring above the breaker. Power loss is 12.5 W maximum, so adjacent devices in a sealed enclosure need that accounted for in the thermal budget. That means it can signal its status to a PLC or safety relay without an add-on module — useful for remote trip indication or interlocking with upstream contactors.
