There is no overload or short-circuit protection — this is a pure disconnector, not a circuit breaker, intended for isolation and switching under load where the upstream device provides the protection. The main circuit connects via busbar lugs on a front terminal arrangement, which keeps wiring organized in a panel and matches the standard 3VA frame-160 footprint.
Rated insulation voltage is 800 V, and the maximum operating voltage is 690 V AC / 500 V DC, so it covers 480 V and 600 V class distribution systems as well as 400 V line-to-line networks. The shunt trip coil draws power only during the trip event; it does not require continuous hold-in current. The 220-250 V DC / 208-277 V AC coil range covers common control voltages in both DC battery-backed systems and AC control transformers. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — the same frame size as the 3VA1 line, so it shares busbar kits and mounting accessories with other 100 A frame-160 devices.
