Great product, safely isolate electrical loads
I used this as a relay to power up my electric winch on my 4x4. Works great. Would recommend.

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.

It works at high current
Installed is as a bypass of my backhoe solenoid. Really need a new starter and solenoid but this is keeping me going so far
