Connection width extension 4p, size 3
Optional accessories for the circuit-breaker series NZM offers a comprehensive portfolio of application options for use world wide. The mounting is always flexible and easy thanks to the modular function groups. Notes: type contains parts for a terminal located at top or bottom for 3 or 4 pole switches. Central drilling for e.g. up to 2 cable lugs per phase. Can be fitted to circuit-breaker with screw connection. Phase isolator and insulation plate are included as standard. distance between pole centers with NZM3(-4)-XKV70: 70mm Hole for control wire exists. Terminals NZM3(‐4)‐XK300 and NZM3(‐4)‐XK22X21 can be retrofitted. Can be used for: NZM3(-4), PN3(-4), N(N/O)3(-4)
