Product Description

Jiuji 3P Automatic Voltage Current Protection Device Relay

This voltage and current protector is designed to provide reliable and intelligent protection for electrical systems against overvoltage, undervoltage, and overcurrent conditions. When abnormal voltage or current is detected, the device automatically disconnects the power to protect connected equipment from damage. Once the electrical parameters return to safe levels, power is restored automatically after a preset delay—no manual reset required.

With precise monitoring, fast response, and stable performance, this protector is ideal for residential, commercial, and industrial applications, especially in areas with unstable power supply. It helps extend the service life of electrical appliances, reduces downtime, and ensures safe and continuous operation.

Terminal

The side features a smooth curved design, delivering a clean, elegant appearance with enhanced safety and handling comfort.

Designed for standard 35 mm DIN rail installation, this product allows fast and secure mounting inside distribution boards.

Equipped with high-quality wiring terminals for stable connections, enhanced safety, and long service life.

Designed for Solar Systems & Unstable Power Grids

This model is specially designed for solar power systems and regions with unstable voltage supply. It provides reliable protection against overvoltage, undervoltage, and overcurrent caused by grid fluctuations, solar inverters, or sudden load changes.

With intelligent monitoring and automatic recovery, the protector disconnects power immediately when electrical parameters exceed safe limits and restores power automatically once the voltage stabilizes. This ensures continuous operation of solar equipment and prevents damage to inverters, batteries, and connected loads.

Ideal for solar installations, off-grid and hybrid systems, and countries where voltage fluctuation is common, this protector helps improve system stability, extend equipment lifespan, and reduce maintenance costs.

If you have any customization requirements, Jiuji Electric is ready to support you. With an experienced in-house engineering team, we are able to design and customize products according to your specific technical requirements, application scenarios, and market standards. From function adjustment to parameter settings and appearance design, we work closely with our customers to deliver reliable, market-ready solutions that truly meet their needs.
