It is a pure disconnecting means — no overload or short-circuit protection built in. The order code includes a shunt trip (left side, 208-277 V AC 50/60 Hz, 220-250 V DC) and one changeover auxiliary switch.
This is a panel-mount disconnector for main incoming or load-break isolation on 400 A circuits. The nut keeper kit on both sides of the main current circuit simplifies busbar or cable connection in a switchboard.
