Rated for constant duty
Use this with my 12K winch on my Jeep JLU. Wired to a factory auxiliary switch it offers an extra level of protection and eliminates a high amperage hot wire running though the engine compartment to the front bumper. I bought this brand based on positive reviews and was going to go cheap on an item that could cause a fire if it failed.

Super SOLID and High Quality
This thing as soon as you pick it up you know its built with quality. I haven't yet installed this in my vehicle but to make sure everything was working good I have test the relay and everything seems to be working good. Only issue I could see with installing this is that it may be a bit large to hide away in a smaller truck or car. I recommend everyone looking to purchase one just to purchase the 500 amp then you can cover all the bases without worrying if you are within the amp rating. I definitely would recommend getting this relay from searching for other ones this one seems the most high-quality.

Works as intended
Bought this to wire my jeeps winch up to my voswitch panel so I can turn my winch on and off with my switch panel. Works great, went with the higher amperage one because winches under high load can pull 400+ amps. Plus I donโt like having a constant positive wire running through my jeep incase of wire rubbing or a fender bender causing a short. Easy to install and wire up if you have a basic knowledge of wiring. Will buy again

My bus hasn't burned down yet!
This replaced a relay in my transit bus that appears to have been replaced with a starter relay that was melting and in the process of having a rather unfavorable outcome. This relay hasn't gotten hot at all, and doesn't fail. My use case is all the aux power items (AC, lights, etc) on a 09 e450 transit bus
