1.About us

   We're specialized in designing and  manufacturing circuit breaker and contactor in China with the  experience  of more than 15 years and with the experience of more than 10 years,manufacturing according to the ISO9001 quality control system guidelines and IEC and EU standard. We help our customers develop the specical products as per their inquiries and OEM service offered.

2.About the product

   1).The  product   is mainly used in circuit with AC 50/ 60Hz, voltage 230V up to 400V, current 1A up to 63A  for protecting cables and  equipment against overload and short circuit.and also for isolation.

   2).The product adopts advanced technologies and the latest materials  to improve its breaking capacity and electrical life.

   3).Highly standard modular design is to reduce variety of parts and improve its reliability.

   4).The feature is compact constructure ,small volume,light weight ,advanced current-limit technology,3KA breaking capacity and convenient mounting and so on.

   5).  The main components(expect those easily disable parts) can last as long as up to more than 30,000 hours.

   6).Products and all key components are finished by precisely machining and accurately assembling, and strictly tested, therefore high quality is reached.
