Moeller® series

Key lock for NZM circuit breakers

2

Key lock based

on cylinder lock

Areas of application:

Available in all sizes of the circuit breaker / disconnector series NZM/N…1,2,3,4. Integrated in rotary handles and rotary door-coupling handles without any particular space requirements Fast assembly without any extra effort as it comes pre-assembled in the handle combination Main and maintenance switches are fast and easy to lock and protect from being switched on again Mechanical lock can be implemented in a space-saving way and with a minimum of assembly effort

This function reliably prevents the respective circuit

breaker/disconnector switch from being switched on and

thus complies with the disconnector requirements in OFF

position pursuant to IEC/EN 60947-1. The locking effect

is directly applied to this circuit breaker by a fi rmly fi xed

cylinder lock combined with our proven rotary handles and

rotary door-coupling handles. To activate the lock the circuit

breaker/disconnector switch must be switched off. The

safety key can only be removed in the OFF position of the

switch.

This is a simple method that enables the user to safely

work on switched-off installations or machines and several

switches can mutually lock each other in a safe way.

Advantages:

• Mechanical mutual locking of several switches. Only the switches with the key inserted can be switched on.

• Main switch and repair / maintenance switch.• e.g.in: trade and industry supply systems Processing industry Ship-building Mining Data centres Back-up power supply systems Telecommunication

ON/TRIP OFF

Example of application: Mechanical mutual locking of two switches. Only the switch where the key is inserted can be switched.

Scope of delivery: One safety lock in each enclosure, with two keyed-alike Ronis keys in a pre-assembled combination with handle kit on the NZM…XD... switch and NZM…XTVD… rotary door-coupling handle kit
