This 3VA2216-7HL42-0AA0 is a 4-pole SENTRON molded case circuit breaker from the 3VA2 series, rated for 160 A continuous current with an ETU320 electronic trip unit. It's designed for line protection — main feeder or large branch in a distribution panel. The trip unit is adjustable from 240 A to 1 920 A, so you set the actual protection threshold to match the downstream load. No undervoltage release, no ground-fault monitoring, no communication module — this is a straightforward thermal-magnetic replacement with electronic precision.
Breaking capacity and selectivity
The interrupting ratings are what make this breaker stand out for high-fault installations: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 4.5 kA at 690 V. That's enough SCCR headroom to coordinate with upstream transformers or downstream panelboards without cascading failure. The 160 A rating holds steady across the full ambient range from 40 °C to 70 °C — no derating needed in a hot enclosure.
Mounting and dimensions
Physical footprint: 140 mm wide, 181 mm high, 86 mm deep. Bolts onto a mounting plate or into a panel cutout — no DIN-rail clip on this frame size. The IP40 front protection means it's fine for a dry indoor enclosure but not washdown areas. Four poles mean it switches all three phases plus neutral, typical for a 4-wire system where you need neutral protection.
