What this MCCB does for your line
The Siemens SENTRON 3VA1010-3ED36-0CC0 is a 3-pole molded case circuit breaker rated for 100 A continuous current, with a TM210 thermal-magnetic release that handles overloads and short-circuits without external trip units. Its interrupting capacity hits 75.6 kA at 240 V and 52.5 kA at 415 V — enough to clear high-fault scenarios on distribution transformers or large motor branch circuits without cascading upstream. The 800 V rated insulation voltage means it's comfortable on 480/277 V or 600 V systems common in North American and European industrial panels.
The breaker carries its full 100 A from 40 °C up to 50 °C ambient. At 55 °C it derates to 96 A, at 60 °C to 94 A, at 65 °C to 92 A, and at 70 °C to 90 A.
