The Siemens 3VA2010-5HL32-0AH0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. The interrupting ratings are the key fit decision: 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.
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard MCCB footprint that fits most DIN-rail or panel-mount enclosures. Trip indicator is present for quick fault isolation without opening the cover.
