FAQs

 

What is the main function of the NZK1-32 Change-over Switch?

It enables manual transfer between two power sources—for example, between grid and generator—to ensure uninterrupted power supply and safe switching in low-voltage systems.

 

Where is the NZK1-32 typically used?

It is ideal for residential, commercial, and small industrial applications, especially where dual power or backup systems are installed.

 

How is the NZK1-32 installed?

The switch mounts easily on a TH35-7.5 DIN rail. Before energizing, operate it several times to confirm smooth and reliable switching.

 

What operating conditions should be maintained?

It performs reliably between −5°C to +40°C and up to 2000m altitude. Ensure it’s protected from moisture and rain during storage and use.

 

What variants are available?

Two models are available: NZK1-32/1 (1P) and NZK1-32/2 (2P), suitable for single-phase or double-pole switching configurations.
