Review on ⚓️ Optimized for SEO: Blue Sea Systems 7035 187 Series Marine Electronics by John Brazington

I bought the 150 amp version and did the same test as the cheaper brands of these switches. Other brands clip 80 to 90 amps (sometimes even less). With this brand I was able to run at 120A for about 45 minutes before having to reduce the current because my test unit was getting too hot. They really work at their rated current. Don't waste your money on cheaper brands, buy them if you want switches that actually match their specs. Also, the measured resistance was about 0.0005 ohms. Much better than other brands I've tested. Very good pads around the spikes for very low contact resistance.
