141501000099A002 Relay Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The Sany 141501000099A002 relay is a genuine original electrical component from Sany Heavy Industry. It is a core switching control component in the air conditioning electrical control system of construction machinery, widely compatible with the air conditioning control systems of Sany large excavators and various heavy-duty construction machinery. This relay primarily handles the on/off switching and load switching functions of the air conditioning fan, evaporator, temperature control system, and refrigeration circuit. Through precise low-voltage control of high-voltage operation, it achieves stable linkage of functions such as air conditioning start/stop, fan speed switching, and refrigeration regulation, making it a key component ensuring the accurate operation of the air conditioning electrical control system. The product strictly adheres to Sany’s original electrical design standards; its pin specifications, mounting dimensions, circuit parameters, and plug-in interfaces are completely matched to the original vehicle’s electrical system. No modification or rewiring is required; it can be directly installed in its original location, effectively solving common electrical faults such as air conditioning not starting, intermittent operation, poor circuit contact, load tripping, and control failure. Designed for the harsh working conditions of construction machinery, including high vibration, high dust, alternating high and low temperatures, and strong electromagnetic interference, this relay adopts a precision electromagnetic control structure and a reinforced protection design. It features vibration resistance, interference resistance, high temperature resistance, and resistance to contact erosion. It has sensitive switching response and stable operation, and can ensure the safe, accurate, and efficient operation of the air conditioning electrical control system of construction machinery for a long time. It is a high-quality original part for repairing air conditioning electrical faults, replacing old relays, and maintaining circuit systems in construction equipment.
