  • Simple,easy,durable.
Color: WA30A
A simple fuse is easy to install. I wish these were available 50 years ago when I was a full-time mechanic.

  • Way Better than Getting an In-Line Fuse !!
Color: WA40A
This is waaaay better than getting an in-line fuse. You NEVER have to buy another fuse again, because it has NO fuse . Also, you can cut-off the power to you amplifier, if you need to adjust your cross-over sound settings for your mid-rage and high speakers. My sub is a 15-year old Infinity BassLink. And I am running it with a Pioneer AVH NEX-2550 head unit. My stuff is BANGIN' HARD now. This is because the 30-watt blade fuse I originally had under the hood was weak and restricting proper flow to my amp. With this breaker my 15-year old sub sounds waaaaay better. I never new it could BANG that good. And sounds cleaner too. =========== INSTALLATION was a breeze. 1) - UN-hook just the positive cable and put the terminal on a cloth so it does not touch any metal by accident 2) - Strip about 1/2 inches of the protective sleeve off the Audio cable for both the ends that will go into the Fuse Breaker Switch 3) - Jam the wire as far as it will go into both ends of the breaker 4) - Screw down the wire cables with an allen-wrench. 5) - Make certain to have the clear and red protective caps screwed back on for a water-tight seal 6) - NEVER, EVER install this breaker close to your amplifier. You just need to install it as close as you can to the car battery. About 6-inches of cable or so. 7) - For SAFETY, I made certain to have the breaker switch in the "OPEN" position BEFORE I attached it to the battery terminal. 8) - Connected to the battery terminal. Turned on the car and radio. 9) - Closed the breaker switch 10) - Viola! All done, son !! =========== ADDITIONAL NOTES : For my 200 Watt amplifier, I got a 40 AMP. IMPORTANT: Make certain to get just the right amp amount that SAFELY matches particular wattage of your amplifier. NOTE: Purchasing too high of an Amp for the breaker is like having NO protection at all. Hope all this helps. ... show more

  • Will rust! Not for under the hood!
Color: WA30A
Installed a couple years ago under the hood in my truck for an amp installation. It's all rusted and the mechanism has desintegrated. So not good for any area where moisture might be present. Will not buy again cheap!

  • Works great on my DIY E-Bike battery
Color: WA50A
As the title says, I used this on my ebike battery build. I mostly use it simply as an on/off switch for the battery terminals, but it doesn't hurt to have the added safety of the breaker. In my situation, the BMS on the battery should trip before this breaker, so this just serves as a backup.
