141501000099A002 Relay Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 141501000099A002 relay is a core switching component in the electrical control system of Sany wind turbines. It is specifically designed for auxiliary circuits such as internal and external air conditioning, cooling fans, and servo motors, responsible for circuit on/off control, load switching, and circuit protection. It effectively solves common problems of ordinary relays such as contact erosion, delayed switching, poor contact, and high-temperature failure, precisely matching the wind power control logic and ensuring stable operation of auxiliary equipment circuits such as duct regulation and ventilation.
This product adopts an industrial-grade electromagnetic switch structure, featuring excellent contact conductivity, resistance to arc impact, and sensitive switching with no delay. It incorporates overload and overcurrent protection mechanisms to withstand instantaneous voltage and current fluctuations in the circuit, preventing burnout of electrical control components. The entire unit is sealed for dust and moisture protection, making it suitable for harsh wind power conditions such as outdoor sandstorms, salt spray, and alternating high and low temperatures. It features original factory protocol compatibility and standard interface holes, allowing for direct installation without debugging or modification. Suitable for routine maintenance and replacement of turbine units, as well as bulk assembly, it is a highly reliable original accessory for wind power control systems.
