What this MCCB delivers
The Siemens SENTRON 3VA2216-8JP42-0KG0 is a 4-pole molded case circuit breaker rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. It's designed for line protection, meaning it sits on the feeder or main distribution side of a panel, not on a motor branch. The breaking capacity is the headline: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. That's high-interrupting capability for a 160 A frame — it handles fault currents on large transformers or busway drops without cascading upstream. The unit includes a shunt trip (STL) auxiliary release and one auxiliary switch plus one trip alarm switch, so it can signal a PLC or annunciator on trip. Communication function is built in, which on this platform typically means PROFIBUS or PROFINET connectivity for remote monitoring and coordination.
Panel fit and footprint
The breaker measures 86 mm deep by 140 mm wide by 181 mm high. That 140 mm width for a 4-pole frame is standard for this SENTRON platform — it matches the mounting footprint of other 3VA2 breakers, so if you're swapping in a panel that was laid out for a 3VA2163 variant, the busbar and lug positions line up without re-drilling. The depth is shallow enough for most 200 mm deep enclosures. Maximum power loss is 25 W, so heat dissipation inside a sealed cabinet is manageable — no forced cooling required for a single unit in a typical distribution board.
