China TH-T65 54A Overload Relays Manufacturer, Supplier, Factory

SPX is a well-known electrical brand in China. Our high quality DC Frequency Converter 380v to 220v is a specialized power conversion equipment that converts industrial grade high-voltage direct current energy into standard civilian or commercial low-voltage alternating current. It is designed specifically for systems with 380V DC busbars or high-voltage DC sources, efficiently and stably converting DC power into 220V, 50Hz pure sine wave AC power.

The SPX high-quality 21A AC Electrical Contactor is a universal electromagnetic control switch with a rated operating current of 21 amperes. It is designed specifically for safe and reliable switching of small and medium power three-phase or single-phase AC loads. It drives mechanical contacts through electromagnetic coils to achieve remote and automatic opening and closing operations of the main circuit by the low-voltage control circuit. Its core value lies in providing a performance matched, cost-effective, and durable basic control component for electric motors, heating equipment, and other loads with a rated power of approximately 11 kW (calculated as 380V three-phase). It is one of the most common and classic control units in modern electrical control cabinets and power boxes.

SPX Electric factory's advanced AC Contactor Din Rail Mount was developed to adapt to the global standard of 35mm DIN rail installation. It is the core electrical component for modern industrial control cabinets and distribution boxes to achieve fast, neat, and modular installation. It combines the powerful on/off function of contactors with the convenience of rail installation, completely changing the tedious process of traditional panel drilling installation and greatly improving the efficiency of electrical assembly. It is the preferred basic component for building compact, reliable, and easily expandable electrical systems.

At SPX factory, you can wholesale 2 Pole 125A AC Molded Case Circuit Breaker, which is a specialized electrical switchgear that provides comprehensive protection for single-phase or phase separated high current main circuits. It integrates overload protection, short-circuit breaking, and line isolation functions at a rated working current of 125 amperes, and is designed specifically for safe management of high-power loads in AC distribution systems. Welcome to China for sightseeing. If you are interested in our products, we hope you can visit our company!

SPX factory offers a high quality 4P 250A 200A Molded Case Circuit Breaker, which is our direct response to the increasingly complex power distribution environment and constantly improving safety standards. We ensure that every product undergoes rigorous testing, and its four pole synchronous breaking performance and N-pole protection characteristics meet and exceed the standard requirements. We not only provide products, but also are willing to share our experience in designing quadrupole systems, assessing harmonic effects, and coordinating protection to help you build a safer, more standardized, and more reliable distribution system. Choosing SPX means choosing an uncompromising commitment to safety and standards.

SPX factory's high quality Overload Protection Thermal Relay is a protective device designed to prevent winding overheating and damage caused by prolonged operation of electric motors beyond rated current. Its core lies in utilizing the physical characteristics of bimetallic sheets bending under heat, simulating the heating model of motors, and providing precise matching inverse time overload protection. It monitors the motor current and outputs a signal to disconnect the control circuit when the overload continues to reach a dangerous threshold, thereby achieving non instantaneous, heat accumulation based protection. It is an economical, reliable, and essential classic protective component in the safe operation of motors.
