Since 2017 we've been trying to find something better than the Kaizen Relay - but it doesn't exist. The nearest competitors require two outputs in parallel to match our 40 Amp rating, and it goes far beyond that! We've tested head-to-head with the "other" Solid-State products on the market and even if you can look past the screw terminals, competing products will overheat within seconds of pulsing a fan or a pump! It's not even close!
The design of the relay hasn't changed in 50 years. They either have exposed male prongs or a bulky weatherproof connector. Both require different crimpers for installation. Fine. But not great.
