FAQs

 

What is the main function of the NXU-I+II Surge Protective Device?

It protects electrical systems and equipment from lightning-induced surges and transient over-voltages, ensuring safe operation of downstream loads and sensitive electronics.

 

Can the protective module be replaced without shutting down the circuit?

Yes. The removable protective module allows quick replacement of damaged units without disconnecting power, maintaining continuous operation.

 

What differentiates the “F” version from the standard model?

The NXU-I+II /F variant includes a remote alarm contact, enabling remote fault monitoring and integration with intelligent control systems.

 

Where can this SPD be used?

Ideal for main distribution boards, industrial switchgear, renewable-energy systems, and building service panels where both Class I and Class II surge protection levels are required.

 

What maintenance indicators does it provide?

A color-coded window (green/red) indicates working or fault status. When red appears, simply replace the protection module — no full system shutdown is needed.
