FAQs

 

What is the main function of the NJVA1 Voltage and Current Protector?

It monitors voltage and current in AC systems, disconnecting the circuit during overvoltage, undervoltage, or overcurrent conditions and automatically reconnecting when parameters return to normal.

 

What is the adjustable voltage range?

Users can set the undervoltage cut-off between 140–200V and overvoltage cut-off between 240–300V depending on system requirements.

 

Can the overcurrent protection be adjusted?

Yes, the overcurrent cut-off is adjustable from 1–63A or 10–100A, depending on the selected model.

 

How is the NJVA1 installed?

It’s designed for standard DIN-rail mounting, suitable for quick integration into distribution panels.

 

Where is the NJVA1 typically used?

It’s widely used in power distribution systems, substations, generator panels, and factories to protect sensitive electrical equipment from damage caused by voltage or current anomalies.
