Recently we needed some polymer air circuit breakers and we did want to buy from some reputed supplier. So, we asked our trading partners and the suggested Compaq international. We enquired and found that this is an iso certified company. Due to that we placed out order with them and got our cicuit breakers. It was good and they have performed well. We like their products so much. We are thinking of placing more air circuit breakers. The customer suopport team is very helpful. They came around to answer our questions regarding the specifications of their products. We are very happy with this company.
