FAQs

 

What is the purpose of the NZK2-32 Change-over Switch?

It allows manual transfer between two power sources—for instance, between the main grid and a backup generator—ensuring continuous power supply in low-voltage systems.

 

Where is the NZK2-32 typically used?

It’s ideal for residential, commercial, and small industrial applications, particularly in distribution boxes and control panels that require safe and reliable source switching.

 

How is the switch installed?

The switch can be mounted on a TH35-7.5 DIN rail, with an allowable tilt of ±5° from vertical. Before energizing, operate it several times to confirm smooth and reliable action.

 

What is the difference between the 1P and 2P models?

1P: Single-phase switching.

2P: Dual-pole configuration for two simultaneous circuits, providing extra safety and flexibility.

 

How many operations can it withstand?

The NZK2-32 supports up to 10,000 electrical operations, ensuring long service life and reliable performance under frequent switching conditions.
