The Siemens 3VA2010-5HN36-0HC0 is a SENTRON molded case circuit breaker (MCCB) rated for line protection, 3-pole, 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. The interrupting capacity tells you where it can sit in the fault-current hierarchy: 187 kA at 240 V AC means it handles high-fault service-entrance or large-feeder duty on 240 V systems; at 415 V and 440 V it still holds 121 kA, enough for most industrial distribution panels. At 500 V it drops to 75.6 kA, and at 690 V the rating falls to 3 kA — that last figure signals it is not intended for 690 V main-breaker service; at that voltage it is a downstream branch breaker behind a current-limiting device.
Built-in accessories and panel fit
The 105 mm width (4.13 in) and 86 mm depth (3.39 in) mean it occupies standard MCCB panel space; height is 181 mm (7.13 in).
