Thermal overload relay is protective device, that is a optional accessory for AC contactor. It is used to protect the motors or power circuit from overheating and getting damaged by the prolonged overloads or phase failures. It is designed with temperature compensation, overload and phase failures protection, and automatic and manual reset function. And the thermal overload relay is with function to set the precise current for specific application. Yijia is China AC contactor and thermal overload relay manufacturer.

The Auxiliary Contact Block is a modular electrical component for AC contact, designed to expand the functionality of contactor by providing additional control contacts. Compatible with standard industrial switching devices, it enables auxiliary signaling, interlocking, and circuit monitoring in AC power systems. Synchronized operation with main contactor, NO/NC contact configurations available, easy integration with standard AC contactor. And it is applied in interlocking, signaling, and control circuits.

General Purpose Relay is a electromagnet relay, that is used to switch the circuit in various electronic and electrical applications.The design purpose is that allows a low-power control signal to control a higher-power load circuit. It consists of pure copper coil, silver alloy contacts, High-strength armature. With the compact design and socket, it is easier to install and maintain. The control volt is range from 5V to 380V to choose, to suitable for different application. The general purpose relay made in china for low-cost and high-quality.

High Current Relay is a electromagnet relay, an electrically operated switch designed to control large electrical current, beyond the capacity of general purpose relay. It is used in applications where high-power circuits need to be controlled by a low-power signal. This type relay is essential in systems requiring the management of heavy loads, such as industrial machinery, automotive systems, power distribution, and renewable energy systems. The control volt is range from 5V to 380V to choose, to suitable for different application. The High Current Relay made in China for low-cost and high-quality.

The Relay with Lockable Test Button is a type of electromechanical relay. It is an advanced electrical switching device designed for applications where manual testing, secure operation, and reliability are critical. It combines the functionality of a standard relay with the added convenience of a manual test button and a locking mechanism to prevent accidental or unauthorized activation. This type of relay is widely used in industrial, commercial, and safety-critical systems to ensure proper operation and enhance safety. YIJIA relay with lockable test button is easy-maintainable and low-cost.

Relay socket the accessory for general purpose relay, to make it easier to install, replace, or maintain relay without complex operations. It offers a convenient interface for connecting the intermediate relay to external wiring. It is designed with din rail mountable. It has multi types to choose, 8 pins for 2NO2NC relay, 11 pins for 3NO3NC relay, 14 pins for 4NO4NC relay. It uses engineering plastic materials for durable, heat-resistant. Advanced relay socket is made in china, and YIJIA offer free sample.
