Remote operator, 220-250VDC, for 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: for remote switching of circuit-breakers and switch-disconnectors. ON and OFF switching and resetting by means of two-wire or three-wire control. Local switching by hand possible. lockable in the 0 position of the remote operator with up to 3 padlocks (hasp thickness: 4–8mm). Can be synchronized. Cannot be combined with mechanical interlock. Cannot be combined with dual auxiliary switch M22-CK11. Can be used for: NZM3(-4), N(N/O)3(-4)

Description	For remote switching of circuit-breakers and switch-disconnectors. ON and OFF switching and resetting by means of two-wire or three-wire control. Local switching by hand possible. Lockable in the 0 position of the remote operator with up to 3 padlocks (hasp thickness: 4 – 8 mm) Can be synchronized   Please note during engineering: Three-wire control Terminal 70/71:   NZM-XR: Contact loading according to technical data NZM2-XRD: Full current flows through the contact during make and break! RMQ series contact elements can be used for the NZM2(3.4)-XR(D)...remote operators.       Two-wire control Terminal 75:   NZM-XR: Operational readiness signal when cover closed and not locked. NZM2-XRD: Operational readiness signal when sliding switch set to Auto. Sliding switch with three positions: Manual/Auto/Locked for reliable differentiation of connected positions. AC-15: 400 V; 2 A DC-13: 220 V; 0.2 A     Three-wire control with automatic reset to the 0 position after the switch has tripped       Switching cycle:   NZM2-XR NZM3-XR NZM4-XR The time interval between OFF and ON is 3 seconds. On commands received during the time interval are ignored within the first 3 seconds after switch off.     Parallel remote operator connection
