Frequently Asked Questions

What is an Arc Fault Circuit Interrupter (AFCI)?

An AFCI is a safety device that detects dangerous electrical arcs in a circuit and disconnects the power to prevent fires. Unlike standard breakers, AFCIs can identify high-impedance faults that may not draw enough current to trip a regular breaker.

How does the JGDL-63 automatic reconnection protector work?

The JGDL-63 monitors voltage continuously. If overvoltage or undervoltage is detected, it disconnects the load. Once the voltage returns to a safe range, it automatically reconnects the circuit—eliminating the need for manual reset.

Can I customize products for my brand?

Yes. We offer comprehensive OEM and ODM services. Our experienced R&D team can customize designs, packaging, and labeling to meet your brand’s specifications.

What certifications do your products have?

Our products comply with GB standards and have obtained over 100 patents. We follow strict quality control processes to ensure reliability and safety in all our devices.

Where are your products used?

Our protection devices are used in residential buildings, commercial complexes, industrial plants, data centers, hospitals, and renewable energy systems worldwide.
