What this MCCB carries and where it fits
The Siemens SENTRON 3VA1116-6EF32-0KH0 is a 3-pole molded case circuit breaker rated for line protection — meaning it sits at the incoming feed of a distribution panel or as the main disconnect for a branch, not as a motor-protective device. It carries 160 A continuously at 40 °C ambient, with a thermal derating curve that drops to 150 A at 70 °C, so if your enclosure runs hot you need to account for that headroom. The interrupting rating hits 220 kA at 240 V AC, 154 kA at 415 V, and still holds 17 kA at 690 V — that's enough for high-fault utility feeds without cascading upstream breakers. Insulation voltage is rated 800 V, so it's comfortable on 480 V and 600 V class systems.
Panel fit and integration
The breaker measures 70 mm deep by 76.2 mm wide by 130 mm tall — a standard 3-pole MCCB footprint that drops into most SENTRON distribution blocks and panelboards without re-drilling. It ships with a shunt trip (STL) and two auxiliary switches plus one trip alarm switch (HQ), so you can wire remote trip and status indication without adding external relay logic. Power loss is 38 W max at rated load — factor that into enclosure thermal calculations if you're stacking several breakers in a sealed cabinet.
