Features： 1、Interlock Mounting: The unique male and female slot interlocking mounting design on the edge of each socket connects relays together and manages cables easily, providing a clean and tidy installation. 2、Heavy Duty: Large capacity, high capacity, heavy duty on off relays. But never exceed their capacity and try to keep them 10 to 15 per cent below actual rates. 3、Premium Material: Starter relay is made of nylon, metal and copper, with great thermal stability, resistance to arc erosion and melting, long lifespan, great resistance to soldering and abrasion. 4、Two Copper Wire: With two pure copper wires, the electrical conductivity, tensile strength and loss rate are much better than other materials, ensuring reliable and safe operation. 5、Scope of Application: 4 pin starter relays are suitable for 12VDC automotive circuit systems, suitable for cars, motorcycles, car starts, motors, power supplies.
