NJVA1 Voltage and Current Protector

NJVA1 Voltage and Current Protector

The NJVA1 voltage and current protector is an intelligent modular protection device designed for 230V AC, 50Hz systems with rated currents up to 100A. It automatically monitors and adjusts for overvoltage, undervoltage, and overcurrent conditions, quickly cutting off power to prevent equipment damage. When voltage or current normalizes, it reconnects the circuit after a preset delay, ensuring uninterrupted operation in unattended environments.

 

With an inbuilt real-time voltage/current display, NJVA1 is ideal for AC power systems, generator sets, substations, factories, and machine rooms, protecting equipment from grid fluctuations, sudden power failures, or operational errors. This protector enhances safety and reliability in industrial and commercial electrical systems.
