  • “A Pro’s choice.”
I always use Din rail products. It’s an international standard and makes your job much easier and tidy. I bought this Miniature Circuit Breaker for a small project I was working on: a secondary EV charger installation. The location of this charger is pretty far from the house, so I decided to install a second panel close to the location with a circuit breaker. Typically, I buy cheap circuit breakers, but for this particular application, I needed something really safe and reliable. I did some research and decided that the Westinghouse Miniature Circuit Breaker,50A three pole, would be the right option for me. With it, I can interrupt the neutral and each phase. The build quality is good and it can host 6 gauge wires easily and snug. It holds the 40A of the charger without any problem and the circuit breaker doesn't get warm, as it should be. I can’t say anything about reliability, since I just installed it, but I will update my review if it fails. ... show more

  • Westinghouse Breaker
Works as described, not much else to say, it is a circuit breaker.
