The 140 Amp Circuit Breaker will work as a substitute to your systems 140 amp fuse(s). If your amplifier(s) fuses add up to 140 amps in your system, this one is for you.

The best thing about a circuit breaker is once you buy it, it will not "blow" as is the case with fuses. Call it a long-term investment...

With the click of a button, you can reset the circuit (no switching of fuses, etc.) and your system will be pounding seconds later!

Installation is a snap as you place the circuit breaker between the battery and component.

Key Features:

  • Matches up with systems rated at 140 amps
  • Can be used with 1 or more amplifiers
  • Example Application: 2 amplifiers; 1 has three 30 amp fuses and the other has two 25 amp fuses (30A + 30A + 30A + 25A + 25A = 140A)
  • Saves time, money, and hassles of switching blown fuses
  • 1-year warranty

Cheap build quality

I hope it works better than it feels like it would. Feels very cheaply built. I wouldn't be surprised if it fails.
