About this part, "The Cole Hersee 24143 is a heavy-duty 12V 200A continuous-duty solenoid relay used to switch high-current DC loads from a lower-current control circuit, making it a common fit for battery isolation systems, auxiliary power circuits, RV and marine electrical systems, industrial equipment, liftgates, winches, pumps, and other heavy-duty vehicle or machinery wiring applications. This model is a 4-stud, insulated, normally open SPST solenoid; the later 24213 is the direct successor to the 24143, with the same general form factor and electrical role. Its continuous-duty design makes it well suited for applications where the relay may remain energized for extended periods rather than only momentary cranking duty. Our unit has been tested and verified working, so it is a solid option for buyers needing an OEM replacement, a spare for an existing system, or a dependable relay for a custom 12V high-current control setup."
