1.The user should responsible for the quality problem caused by taking the products apart or adjust the tripping parameters without permission.
2.Touch the uninsulated bare part is not allowed when breaker is energized state.
3.Make sure reliable connection to prevent the abnormal heating of terminals. That can cause fault operation of breakers or terminal damage.
4.Please remove the cover before installation, details please refer to Product Specification.

Wuhan Unique Mechanical and Electrical Equipment Co.,Ltd, base in Wuhan, China and have warehouse in Shenzhen and Shanghai, and agent in HongKong. We engaged to 5G network base designation and construction since the year of 2011, after more than 10 year experience in 5G and 3G broadcast base equipment and materials suppling, we now had build a mature supplying system for BTS base DC power supply System, along with the SMPS rectifier modules, BTS cabinets, BTS room including Air-conditioning, Feeder window, Cable ladder, Grounding. Besides the indoor equipment, we also experienced in Feeder cable, Feeder Jumpers, Feeder clamps, waterproofing kit and grounding kits. Besides the BTS materials, the fiber cable and accessories like outdoor/indoor fiber cable, patch cord, CPRI cable, testers and splicing machines and enclusures are also our main field. During our development, we have build good relationship with some famous brand in Rectifier field like Vertiv/Emerson, Delta/Eltek, Eaton, Huawei, ZTE, YOFC,Hengxin, EXFO etc, we warmly welcome your inquiries if there is anything related to the telecommunication and will serve you with our skills and experience.
