FAQs

 

What is the primary function of the NXU-II G Surge Protective Device?

It safeguards electrical systems and equipment from lightning surges and transient overvoltage, preventing damage to sensitive components and reducing downtime in power networks.

 

In what environments can the NXU-II G be installed?

It’s suitable for residential, commercial, and industrial low-voltage systems, including main distribution boards and sub-panels, especially where surge events are frequent.

 

What grounding systems does it support?

The NXU-II G can be applied in TN-S, TN-C, TT, and IT systems, offering flexibility for various regional and project requirements.

 

How does the user know when to replace the module?

The SPD features a visual indicator that turns red when the protective module fails. The removable design allows easy replacement without cutting off the circuit.

 

Is there an option for remote monitoring?

Yes. The NXU-II G/F version comes with a remote signaling port (auxiliary contact) to monitor SPD status remotely via building management or control systems.
