High Power Relays 12V

A mini relay can only handle a limited number of amps and cannot cope with power surges. So sometimes a mini relay is not enough, for example when you want to use it to switch on your boat’s starter motor. Then you need a high-power relay. Below you will find high-power 12V relays that can handle a basic current of 200A. Briefly, some of these relays can handle as much as 800A.
