Solid breaker. Very easy to cut the power to the back if needed.

Love it

No more fuses to mess with. Needing to mess with the power wire just hit the red button, opens the contact inside stopping power flow. That simple. If I get lazy and don't hit the breaker and arc it by accident, no replacement of anything. Judy reset the breaker. Wonderful

Great Circuit Breaker for my trunk amps..

I have this breaker connected via my 0 gauge power wire to my (3) XS trunk batteries. When I need to trickle charge them i can easily turn off the circuit breaker with ease. Its a quality product and has a good feel to it. Its a good buy!
