250A Relay, 12VDC Continuous Duty SPST 4-pin High Power Relay

Put this relay in my truck. Attached it so the auxiliary power closes the circuit. So I could run off road lighting. Been installed for about 3 years now. Solid and trust worthy for me.

If you are wondering exactly what this relay provides in terms of electrical design and implementation. Delighted to find solid copper internals, terrific dual brade, very flexible, stranded, woven ~8 AWG copper conductors from terminal #30 , a ~1/4 inch copper lug to activated contact. Terminal 87 of relay switch side provides a solid bar of copper rod 0.35 diameter with high temp contact on switch end. Plated high temp contacts are on both sides of high current switch as activated by relay. Relay operates well at 10 to 12 volts, with crisp aligned and swift magnetic force closure of switch. No bounce. Relay appears to be ok margin at up to maybe 220 volts as the base of the relay depends upon a piece of 0.07 inch thick plastic as isolation from 12 volt enamel coated solenoid wires AWG ~ #34 as connected to pins 85 and 86. Thermoplastic is higher temp, suitable wall strength, leg mount points may soften or melt at continuous duty of max current rating of device. For my application to deliver 200 A in a few milliseconds the device is well suited. YMMV

So far no problem, used on daily vehicle to turn on and off 1200 amp for subwoofers. Highly recommended

It’s perfect! Bought this for my sxs to control a secondary fuse block I put in for accessory lights/radio ect. I used a different brand the first time and it was all metal. It would get pretty hot and lasted about 3 months. This one works flawlessly, no heat and has been installed for almost 2 years!

I've had this relay for a couple months now put in through some heavy use. I use this on my 03 ranger i did electric fan conversion, and it's holding up just fine, still highly recommend pretty reliable relay i've also gotten it wet a couple times and it still holds strong.

I first tried the 40A small Relay which got too hot at 12V, 25A. Then I tried a SSR with heat sink which had unacceptable voltage drop. ... Finally with the irhapsody 250A Relay we are in business (I needed to add a flyback diode across pin 85 to 86). Excellent 👌🏽

I have a Jeep gladiator so space is generally a bit tight. I didn’t really want a huge solenoid but to run a power inverter I was almost convinced I’d have to have one, that is until I found this product. It’s about as big as a general battery cut off switch and does exactly what it was made to do. Easy to install, I do wish it had two mount holes just so I could make sure it won’t shift while hitting bumps. Otherwise does everything I need it to do and saves space in my engine bay for other projects.

this works for my 48v 40a battery which produces 120a at peak

Good product & successful
