Review on ANJOSHI Circuit Breaker 150Amp 50A-300A: Manual Reset Home Solar System Fuse Holder for Car Audio & Amps Protection - 12V-24V DC Reset Fuse Inverter | Replace Fuses Efficiently by Joseph Marshall

So I used mine as a switch and breaker. I put it on a 72v 3000w 45 AE bike and it has never been dropped so I have no idea if it will work when needed. All I knew was that it was a very handy main switch that could handle 50 amps. It has worked great until now when it no longer has pole-to-pole conductivity. If you hit it right and really hit the multimeter's pins, it will unpredictably jump from 1 million ohms to 500 kohms and only sporadically to a few ohms. The only reason I noticed this is because I took it off my bike to test another project that used a 100 watt LED and when I turned it on the LED was only half lit ( like a pair of small 5 volt LEDs together), but when I missed the switch, it worked perfectly. (blinded for a minute) I used it as a switch again, but when you can only turn it on 100 times or less before it breaks, you really want it to protect your project or your home and family. No, too cheap for me and I bought a 60 amp that looked more like a torpedo and broke after 10 cycles. Even if you only use it for the Switch, if you save $10 but spend $10 or so and it breaks in a week, are you really saving money? you have been warned
