Current-Limiting Leakage Over- And Under-Voltage Protector | Digital Display Over- And Under-Voltage Protector | Digital Display Over- And Under-Voltage Protector | Digital Display Adjustable Voltage And Current Protector | Dual-Display Over And Under-Voltage Protector Jgiv-63l

I. Product Introduction

The JGIV series is a current-limiting leakage-type over/under-Voltage Protector. It also provides over-voltage, under-voltage, short-circuit, leakage, and comprehensive protection. With advantages such as modularization, intelligence, and visualization, all protection parameters including over-voltage, under-voltage, and leakage protection can be set according to power usage requirements, ensuring that when faults such as over-voltage, under-voltage, short-circuit, or leakage occur in the line, the protector can instantly cut off the power supply and protect electrical equipment from damage.

   This series of products features a compact structure and an attractive appearance, with standard DIN rail mounting. It is mainly suitable for household power distribution, school dormitories, rental housing, and other occasions.
