The Siemens SENTRON 3VA2110-5HL32-0HA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, designed for line protection in distribution panels. The rated insulation voltage is 800 V, so it's comfortable on 480 V and 600 V class systems.
This breaker delivers 187 kA at 240 VAC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The steep drop at 690 V tells you this is a 240–500 V class device; at 690 V the interrupting rating is low enough that you'd need a different frame for high-fault 690 V panels. For typical 480 V industrial distribution, 121 kA covers most high-fault scenarios without cascading upstream.
Thermal performance — flat derating to 70 °C
The continuous current rating holds at 100 A from 40 °C all the way to 70 °C — no derating curve to calculate. That's unusual for an MCCB; most frames start dropping at 50 °C.
The 3VA2110-5HL32-0HA0 measures 181 mm high, 105 mm wide, and 86 mm deep. That 105 mm width is standard for a 3-pole SENTRON 3VA frame — it mounts on a DIN rail or bolts directly into the panel backplate.
