What this MCCB delivers for your panel
The Siemens SENTRON 3VA2216-8JP42-0AA0 is a 4-pole molded case circuit breaker rated for 160 A continuous current, carrying a 440 kA interrupting capacity at 240 V AC — enough to handle high-fault utility feeds or large transformer secondaries without cascading upstream. It ships with the ETU550 electronic trip unit, which gives you adjustable long-time pickup (Ir), short-time, instantaneous, and ground-fault protection curves — the kind of selectivity you need for a distribution main or a large motor control center feeder. Rated insulation voltage is 800 V, so it's comfortable in 480 V or 600 V class panels with headroom to spare. The 160 A rating holds flat across the full operating temperature range from 40 °C up to 70 °C — no derating curve to watch when the panel runs hot.
Mounting and integration
The breaker measures 140 mm wide by 181 mm tall by 86 mm deep — a standard SENTRON 3VA2 frame footprint. Front-face protection is IP40, meaning tools and fingers stay out of the live terminals once the cover is on, but the body itself is not sealed against hose-down — mount it inside a rated enclosure if the environment is wet or dusty. The breaker includes communication functionality, so it can report status and trip events to a higher-level control system without adding a separate module.
