The Siemens SENTRON 3VA2110-7HL36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 100 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That 100 A is the assigned permanent current Iu, so it handles the full load without a temperature haircut in a warm panel. The breaking capacity is substantial: 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V — so it clears high-fault currents on the secondary side of a large transformer or in a heavy industrial distribution board without cascading upstream.
Panel fit and protection
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard SENTRON 3VA frame size that drops into the same panel footprint as other 3VA2110 variants.
