High Current 500A 12V DC Starter Relay, SPST Contactor for Car Starter

Discover our high-current relay, an essential component for 12V automotive electrical systems. Its primary function is to switch high-power circuits. It can be used independently or integrated into a control system for more complex applications, such as managing dual batteries (note: the additional control relay is not included).

This relay is designed to extend the life of your main battery by preventing premature discharge.

Made from water-resistant black phenolic plastic, it provides durable protection in a variety of conditions.
