Key features

• •Function: Our relays utilize a low-voltage, high-voltage control design. This allows low current (coil side) to safely control high current (contact side), effectively protecting circuits and driving high-load devices such as motors and solenoid valves
• •4-pin and 5-pin: This standard relay is available in two models: a 4-pin (JD2912-1H) and a 5-pin (JD2912-1Z). Both models support 12V/14V DC operating voltage and a 40A high-current load capacity, meeting diverse circuit control needs
• •Safe and Reliable: This auto relay features a fully sealed structure that's waterproof and dustproof (with a high IP rating). The flame-retardant plastic casing is heat-resistant and reduces the risk of short circuits. The brass pins and silver contacts enhance electrical conductivity and reduce heat loss
• •Wide Applications: Our 12V 40A relays are compatible with a high 40A load capacity and can drive high-power devices such as electric fans, fuel pumps, and water pumps. They're suitable for retrofitting or repairing cooling systems, upgrading audio speakers, and controlling trunk electromagnetic locks
• •Packaging Included: Our relays measure 2.05 x 1.13 inches, with two relays per set for easy portability and storage. Plug-and-play operation requires only wiring for installation or replacement
