Junray Electrical, as a professional Manufacturer, Supplier and Factory of Surge Protective Devices in China, focuses on the field of lightning overvoltage protection. We are dedicated to solving the problems of lightning strikes and overvoltage damaging equipment in power distribution lines. We can discharge surge currents and limit overvoltages. With a small size and high cost-effectiveness, it is suitable for various scenarios such as factories, photovoltaics, and communications, and supports customization. It is the standard equipment for lightning protection.

In low-voltage high-current distribution systems, using expensive circuit breakers for simple isolation not only wastes the budget but also increases the number of fault points due to the complex structure. Junray Electrical, as a leading electrical equipment manufacturer in China, has recently launched the Low Voltage Knife Switch, specifically designed for large current circuits that are not frequently operated. It innovatively incorporates a clay arc extinguishing cover, enabling it to not only serve as a power isolation switch but also safely open and close normal load currents.

Junray Electrical, as a professional manufacturer, supplier and factory of Intelligent Air Circuit Breakers in China, is specifically designed to address the issues of insufficient compatibility and lack of intelligent management for ordinary plastic housing circuit breakers. The rated current range is from 630A to 6300A. It is equipped with an intelligent protection module and RS485 communication function, allowing for remote monitoring and control.

In ordinary commercial and civilian power distribution, expensive PC-level dual power supplies often leave the budget in a tight spot, while simple single power supplies cannot meet the requirements for power continuity. As a leading electrical equipment manufacturer in China, Junray Electrical innovatively adopts a dual plastic-case circuit breaker structure, ensuring the automatic switching function while significantly reducing the procurement cost. The ATS Dual Power Automatic Transfer Switch-CB not only can automatically switch to the backup power supply when the mains power fails, but also comes with dual protection against overload and short circuit.

Junray Electrical is a professional Manufacturer, Supplier and Factory of CJX2 AC Contactor in China. It was specifically developed to solve the problem of the inability to remotely and automatically control the motor by the knife switch. It can remotely and automatically control the start and stop of the motor as well as the connection and disconnection of the circuit. It can be combined with PLC to achieve automatic control. The opening and closing is reliable and the size is compact. It is suitable for low-voltage motors, residential areas and engineering equipment control. Customization is supported. It is a standard component for low-voltage control.

For the switching of load currents within ring networks, the high-breaking capacity typically found in circuit breakers is unnecessary. The FLN36 Sulfur Hexafluoride Switch—specifically developed by Junray Electrical for use in ring main units (RMUs)—utilizes SF6 arc-extinguishing technology to deliver robust arc-quenching capabilities. Capable of reliably switching load currents, it offers a significantly lower cost compared to standard circuit breakers. It serves as a perfect match for ring main units and cable branch boxes, establishing itself as the standard switch component for ring network systems.
