💦 Waterproof Industrial Electrical Surface Mount Circuit Breakers: A Comprehensive Manual for Effective Installation and Maintenance Review

Used as a power switch on an electric bike, this thing worked on 100 degree heat days on any cool wet morning so there was never a problem. Tried turning it on and off once a day, used as a key to turn off the electricity, I'm very happy with this purchase, my old fuse overheated and melted which was corroded by moisture, this one continues to work perfectly

I took one apart to see the inside: 1. The contacts inside are small. I doubt the contacts will withstand 200 amps. They are just too small.2. Completely new! The contacts are already partially burned from the factory!3. There is no DC or AC voltage range on E9 type circuit breakers. They don't have a tuned circuit inside to break the arc. A small plastic flange slides between the contacts, interrupting the arc. It will probably work equally well at 12 VDC or 200 VDC.4. The mechanism that…

I installed it on my self-made solar generator. I placed it between the battery pack and a 1500w pure sine wave inverter. Batteries can run at 150Ah continuously and I needed something to protect my investment. A 1500W inverter split into a 12V system is 125A. So I went with THHN 2/0 copper cable and used this 200A switch. That's a bit of an exaggeration, but I can draw 1500W in my system with no cord heating. This 200A DC circuit breaker works perfectly. It is easy to use and install. It gives
