Good Construction - 12V DC (Max@14V DC) and 30A High Switching Capability. Bosch style 4-Pin SPST (Single Pole Single Throw) Relay. Metal mounting bracket on the electrical relay promotes easy installation.
Wide Application - Wide range of use, greatly used for car lights, fog lamps, wiper, starter, fans, speakers, traction control systems, etc.

All parts are manufactured to stringent quality requirements..
Easy to install, Waterproof design, Effective heat dissipation, with no excess heat issue..
Small size/Low power consumption/High contact voltage/ High sensitivity.
Relays play a large role in the ever increasing amount of electronics in automobiles..
Greatly used for car lights, Indicator light, fog lamps, starter, wiper, fans, speakers, central locking, alarm, electric windows, etc..

Large Capacity Holder Box - A clean storage for many projects, tightly holds up to 5 Bosch-style 5pin relay and a RTT7121 4pin Relays, and 6 ATC/ATO blade Fuses.
Special Mounting Legs - High and low legs are designed to snugly adhere to modern angular engine bays or trunk areas, for the flat surface, please add rubber pad yourself to level out the relay box (DIY installation).
2 Clip-Locks Cover - Easy access to the relays and fuses and securely keep them in place, allowing you to quickly maintain or replace the burnt one, also good protection from water splashes, dust and debris.
ACCESSORIES INCLUDED- Metallic pins are included so you can effortlessly swap out relays and fuses from the back of the fuse relay box..
VERSATILE MOUNTING OPTIONS- Since most modern vehicles have angular/sloping engine bays or trunk areas, we engineered the mounting legs to snugly adhere to these surfaces.
a rubber spacer is also included so you can mount the automotive relay box on flat surfaces too..

Virtual Tach - A dedicated A-to-D converter samples your vehicle’s voltage hundreds of times each second, eliminating the need for a tachometer wire connection..
