60190151 DC contactor Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

This product is the core control component for the DC power supply of the equipment, managing the high current switching of the main circuit and the start and stop of the motor, ensuring the stable operation of the equipment. Its strong magnetic attraction and thorough disconnection prevent problems such as loose circuit connections, arcing, and intermittent power supply, making it suitable for harsh working conditions involving construction site vibrations, fluctuating temperatures, and frequent start-stop cycles.
Original factory specifications and dimensions, with wiring holes precisely matched to the original vehicle, supporting in-situ replacement without modification. Utilizing pure copper coils and heat-resistant alloy contacts, it boasts strong load-bearing capacity and is not prone to sticking. Combined with a sealed protective structure, it is dustproof, moisture-proof, temperature-resistant, and anti-aging. Old contactors are prone to coil weakening and contact erosion, leading to start-stop failures, unstable power supply, intermittent shutdowns, and other malfunctions. Suitable for electrical control maintenance, circuit renovation, and bulk stocking, ensuring a stable power supply circuit for the entire machine.
