The Siemens SENTRON 3VA2010-6HN32-0JA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Its interrupting capacity hits 242 kA at 240 V and still holds 187 kA at 415 V, which puts it in the high-fault tier for a 100 A frame. That kind of SCCR headroom means it can sit ahead of a step-down transformer or a bus feeding multiple drives without worrying about cascading failure upstream. The shunt trip release (STL) is built in for remote emergency-off or undervoltage tripping, though there's no undervoltage release module on this variant.
Spring-cage terminals accept 0.2–2.5 mm² solid or ferruled stranded; strip length of 8 mm avoids whiskers under the cage.
The 100 A continuous rating is flat across the ambient range — that's unusual for a molded-case breaker and simplifies panel thermal calculations. At 690 V the interrupting capacity drops to 3 kA, so this is a 480 V class device in practice. Maximum power loss is 13.5 W — negligible for panel ventilation planning.
