✨✨ Reliable and great quality for the price
I bought this CHTAIXI 32-amp breaker for an electrical project, and I’m honestly impressed with the quality. Installation was easy, it fits perfectly on the DIN rail, and the screws are solid. I’ve been using it for several weeks now and it works very well—no overheating or strange noises. The switch feels smooth when turning it on and off, and the overall build looks durable. I also appreciate that it’s clearly labeled and has good thermal and magnetic sensitivity, which adds extra safety to the setup. For the price, it’s an excellent option, especially for solar systems or home installations that need a reliable MCB.
