  • Multifunctional
Color: WF30A
Rewired boat with using 3 of these, one for each zone. Very handy because they act as circuit breakers and disconnect switches. So when you are done for the day you just push the button and kill the power!

  • Nice breaker just choose location carefully
Color: WF30A
I liked this overall but the rubber nubs to protect the connections only protect the top of the bolt, not the whole connection. Have to make sure this is in a good safe location.

  • Key Safety Feature for Auto Wiring
Color: WF30A
There are a lot of ways to protect a circuit in your vehicle, and the most basic one is a fuse. I like breakers like this one because they give you the option of keeping the circuit off when not in use, kinda like a switch. Power in on one pole and out on the other. It's that simple. Note that these are not all the same: this one is rated at 30 amps for tripping, so you gotta know what's on your circuit to size your breaker. ... show more

Saves trying to find fuses. Easy to use. If the circuit breaks because of a load or issue the circuit breaks and easy to reset.

  • Dangerous component
Color: WF30A
Stay away from this one. Used on my boat. After only 4-5 uses the contacts aren't releasing completely when opened, letting various amounts on current thru, 5 to 12 volts with power off. Warranty has expired but I wouldn't replace it with this brand either way, Dangerous!

Circuit breaker for a trolling motor, Mounted on the top of my marine battery. Hooking it up was easy Have not had any issues to know if it actually works yet or not but I wanted it there for safety, to protect the trolling motor !

put this inline on my solar install. I needed a switch between the controller and the panel, plus this gives me voltage protection. so rather than by a fuse and a switch, this does the job perfectly. You never want to remove battery connections without disconnecting from solar, or you will burn up your controller. ... show more
