These are great little breakers for the price. One arrived broken but they were shipped via Amazon Prime so it was no fault of the seller. Would definitely recommend these to others.

Arrived on time and is exactly what I ordered. I buy Circuit Breaker Fuse and Mega Fuse for my electrical protection. I use Circuit Breakers for branch circuits off the main battery. These branches could be for Audio, EFI computers and even the main electrical connection to the car fuse panel. I've even use these breakers to shut off the car when I leave the car a car show so no one can steal it. I've been very happy with them. The only Con I have is these breakers are not good it high temp locations so keep them away for your exhaust or headers. I had one fail when I mounted it just above my headers even though my hearders were wrapped to reduce heat. Good product overall. Must have and good buy

Running a 2500w continuous pure sine wave inverter off it and after 4 months I've had no issues and it works great I've ran 1.5hp compressors, phone chargers and extension cords of the inverter and the amperage hasn't degraded or lost any power it works great as a safety or just a kill switch for the circuit.
