With Extra Fuse: With a built-in 30A blade fuse and heavy-duty wire for the main contact, this car relay 12v needs no separate fuse holder, saving space and cost. When the circuit is overcurrent, the fuse will quickly blow to cut off the circuit, providing additional protection for automotive circuits and ensuring driving safety
Easy Wiring: For quick and easy connection to loads or accessories, this 4 pin relay features color-coded wires for easy installation and circuit connection. The specific color-coding is: red to connect to power positive (30), black to ground (85), white to contact hair (86), and blue to output normally open (87)
Interlocking Design: To achieve a neat and orderly installation layout with easy cable management and organization, the unique interlocking design of the male and female slots on the edge of each 12v relay socket makes it easy to connect multiple relays together for a clean and tidy relay installation
Solid Construction: Supporting 12V DC (up to 14V DC) and 30A current, this SPST (Single Pole Single Throw) automotive relay features a ruggedized case that is resistant to bumps and high temperatures for smooth, reliable operation and high switching capacity, with a 4-pin design and metal mounting bracket for easy installation
Diverse Applications: For automotive key power control, overload protection, trunk release, power door lock/actuator control, security system and more, this 12v relay with harness is widely used. It can also be used to control lights, fog lights, starter, fan, speakers and other electronic equipment
