TYCO/TE Relay V23232-D0001-X001, 75 A AMP 12 V Volt DC

Used this for a cooling fan relay on an excavator. 40 amp relays would not last. It appears to be well made, and the screw terminals for the high amp connections work far better than the slip on spade connectors.

This is a beast of a relay. Yes, there are other 75A relays that are much less expensive, and I can promise you, they are also 'cheaper'. After having TWO other cheaper 75a relays blow out in my project car, I bit the bullet and got one of these. Haven't had a problem since. Sometimes, you get what you pay for. And if you pay for this guy, you won't be disappointed.

I installed this relay as a disconnect switch of the alternator BAT charging terminal. The alternator is rated at 60 amp output. The relay is controlled by a trunk mounted battery four pole disconnect switch. One of the small poles on the main battery disconnect switch is wired to BAT positive (hot) 3/8 pole on the switch. The relay control wire is wired to the other small pole on the main battery disconnect switch. When the main switch is closed, the relay is energized closing the relay allowing the alternator to charge the battery and run systems. If the engine is running I can now shut off the engine when the main battery disconnect switch is opened it disconnects the large battery cable, and de-energizes the relay at the alternator removing all positive potential from the electrical system. This alows my to keep my ampmeter functional on my original gauge cluster.

cumple funcion

So far holds up to high current cooling fan I have no problems

would recommend to anyone who needs a heavy duty continuous relay

So far so good..... I’m a firefighter so I need to lockout several accessories. It a little warm to the touch, but I’m thinking that’s because I’m drawing min 30 amps continuous for 2 hours a day or more. No disappointments so far.

This product arrived as described & has been working well. Product seems to be reliable to date so i would recommend this to others if it suits your application.
