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,high 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 and therefore high quality is reached.
