    Inline breaker which can accomodate up to 1/2" conductors!
  

*by H***N on Reviewed in the United States on November 1, 2024*

I used this to regulate the flow or 24v into a UPS/inverter to recharge its internal batteries from a main engine alternator.  It doesn't get hot and works well as a shutoff switch as well as current limiter.  The end covers aren't designed to be water or dust resistant, just prevent inadvertent contact with electrical terminals.  The conductor clamps can accept up to 1/2" conductors! Well more than I'm running at 60A, so I used the included reducer sleeve to help keep my smaller wires from getting pushed out of the way by the hex grub screw. A wrench is included for said screw. No screws included for mounting unit to wall, but that's fine.  Everything packed well and working. My only concern is the amp rating, which is printed on the case but not molded into the trigger or plastic anywhere, so might lose its labeling over time.

    works as intended
  

*by T***X on Reviewed in the United States on November 9, 2024*

I use this circuit breaker on my solar panel system to prevent pulling too much current from the system at one time. Just a little failsafe to protect the batteries from an unexpected spike. The circuit breaker feels nice and solid like it's made of some quality parts. The test button and reset lever both work well and smoothly. Both ends of the breaker came with a covers to prevent accidental contacts. Plus it came with an Allen wrench for securing the cabling into both sides. So far it appears to be doing its job and I appreciate the added security it provides. 5 stars.
