Connection, on rear, top 4p
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: part no. suffix and part no. contain parts for a circuit-breaker side at top or bottom for 3 or 4 pole circuit-breakers. O = for fitting at the top. U = for fitting at the bottom. Can be used for: NZM2(-4), PN2(-4), N2(-4)
