Nice 3 phase motor protection circuit breaker at a good price.

Delivered on time and in good condition. I used a CHTAIXI breaker the first time I replaced a breaker. I have since built an elaborate circuit full of these. I use them as switches and over current protection. I have no reason to look at another brand. The range of products is especially great. Here in the US you tell someone you need a 400A dc breaker and they look at you funny. These folks just need to know how many to send.

The lower three wire clamps do not hold the wires tight enough. The wires are falling off no matter high tight you make the wire clamping screws. The flat clamp plates are designed to have grooves to dig into the copper wire as you tighten the screws. I bought three circuit breakers from this suppliers and all three had the same defect.. No grooves on the wire clamping plates!It is a hazard to use these circuit breakers on electrical installation. You don't know that the wire is loose unless you wiggle the wire. Loose electrical wires are hazardous can cause fires.

thqnk you

Good

The attachment lugs even when quite tight allowed stranded wire to twist out due to the design; it has a short grip area, and a single Philips screw.I think that there is nothing defective with the product. I wanted to clarify for other buyers that because of the small area of the terminals, I think that some buyers might have issues with stranded wire. Buyers could use ferrules, lugs, or solid wire, all of which would be gripped more tightly with the existing terminal design.
