BaomainHigh Power Relay JQX-62F-2C Coil Voltage DC 12V 80A DPDT 2NO 2NC Electronmagnetic Relay

Looks good. yes plastic is a little fragile,, but mine weren't broken at all. 80A I don't know, but OK for internittent sure. If you need 80 amps all day long you will have to spend far more for a contactor.

I purchased these high current relay for a UPS project and was surprised at the quality of the relay for the price. They are made in China, almost the exact copy of a more expensive relay I usually purchase. I use these relay to switch sump pumps from the grid to the inverter during power outs. They are "open Frame," but include a Dust cover. Will purchase them again in the future.

Works well and very presentable. Used along with other parts for an auto start generator system when the pre-made store bought ones failed in 2 motorhome

Bought this for a transfer switch. Functions okay and should work. However, one terminal was broken off and the other side chipped. This did not happen during transit as the pieces in the bag did'nt fit and the cover would have to been smashed, which it was'nt. It was simpler to glue things back together in less time than it would have taken to package for return. For the price it is a good buy, but if I hadn't noticed till later it would have been aggravating.

Just what I needed for a electric project I was working on.

INCREDIBLE value for such a heavy duty relay! And it really is heavy duty as advertised. All heavy-gauge copper, huge contacts.

Three laser really good but why sell something if you have so many quantities and Chip them on different days makes no sense
