Review: works great - use these to control power to electronics fuse panels on boats. Good for constant use.
Review: Great value for the price. No complaints after a year and a half - This relay has been in service for nearly a year and a half now in my vintage Jeep. I needed something to take the load off my ignition switch, which I was having to replace about every two years. I thought the ignition was a good quality unit, however, it just couldn't take the load I was requiring of it. This 200 amp relay has, so far, been an "ignition saver" for me. It is a constant duty relay that can easily handle the 60, or so, amps needed to supply power to wipers, heater, stereo, electronic ignition, everything wired through the ignition. Most of the additional wiring gizmos that were sent with the unit(s) are fairly low quality, although, the eyelets were brass, or brass plated. The pigtail spade connectors were insulated, as shown in the online display. Just not USA quality. Regardless, Zero problems to date
