irhapsody Relay 250A, 12V Continuous Duty SPDT 5-pin High Power Relay

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

Just got it a few hours ago. Wired it up and it works perfectly and is very quiet. Have no idea about durability or longevity. Will update later.

Needed to upgrade my duel cylinder auto tire inflator from the week PCB board that fryed. Works great and was easy to rewire.

Used as a main power relay on boat power upgrade. Did get an amperage 2x's higher than what i needed, so far it's holding on constant power on, held for 12 hours solid with no problems

So far so good. Have it installed on my Cummins swap as a keyed power relay via a ground switch inside the cab. Have 4 fans direct wired and 2 radiator fans on a fan controller on it and it handles it no problem. Doesn’t even get hot.Not too sure about longevity but seems to be built well enough to handle a good amount of load. You wouldn’t think it would based on the size of the relay, (about 1.5x the size of a standard 30/40 amp relay) but it does it.

Works good

I'm using this relay to power 12v 700 watt water heater element for a dump load on my solar power. So far it is working flawlessly. Load pulls 50-55 amps, depending on voltage, so I am way oversized, maybe. We will see, as others feel the amp rating is overrated. Depending on what my other loads are during the day, my dump load will run for several hours each day. Relay only gets slightly warm.

Great relay, BUT, the #86 and 85 that are stamped on the coil are opposite on the picture on your listing. Them other issue is there is no flyback diode in this relay. I followed your instructions that you posted and noticed the stamping/diagram was different. So I thought to open it up to verify which was the correct way to wiring it up. Just my two cents. Besides that it is a well made relay.
