Patented products, advanced design!
The KYB3DCT-63 series DC circuit breakers incorporate a number of patented technologies that greatly simplify the structure of the products and enhance their reliability!The electromagnetic trip mechanism of the circuit breaker is composed of integrated coil and multifunctional magnetic yoke. The contact mechanism is composed of separated connecting rod mechanism to replace the conventional variable cell four connecting rod mechanism. The arc extinguishing chamber adopts the design of multi-arc channel. Compared with conventional circuit breakers, the newly designed circuit breakers reduce the number of parts and the number of welding or riveting processes between parts.These new designs are based on the principle of circuit breakers and make one part integrate the functions of multiple parts of conventional circuit breakers through ingenious structural design, rather than reducing the cost at the expense of product performance.These new designs effectively improve the utilization rate of materials, especially save the use of copper, so that almost all copper materials are used in key parts, fully reflect the design principle of good steel used on the blade.At the same time, the reduction of the number of parts and the reduction of welding or riveting process can greatly improve the quality stability of circuit breakers and reduce the quality risk brought by the production process or the material of parts.In short, the new design greatly simplifies the structure of the circuit breaker, to eliminate the original unreasonable design caused by the waste of various materials, while simplifying the production process, reduce the difficulty of production and shorten the production cycle.
Good quality and low price!
The cost of newly designed circuit breakers has been greatly reduced, which is embodied in the following points:
1. The number of product parts is reduced, 15 parts less than the traditional circuit breaker.The reduction of the number of parts not only reduces the cost of materials, but also greatly improves the assembly speed and production efficiency of products.
2. The welding points of the circuit breaker are reduced from 8 to 3, and the riveting points are reduced from 4 to 1.The
reduction of welding and riveting points not only reduces the quality risk of products, but also improves the production
efficiency and reduces the production cost.
3. Comprehensively improve the utilization rate of all kinds of materials, save the use of all kinds of materials, especially
copper, and reduce the material cost of products. Through the above optimization design, KYB3DCT-63 series DC circuit breakers not only improve the product performance, but also greatly reduce the cost of parts, production and management of the product, making our products have a great price advantage compared with similar products on the market, the real cheap.
Solid material, reliable performance!
KYB3DCT-63 series MCB products fully comply with IEC 60947-2 standard.The conductive parts inside the product are all made of sufficient amount of silver-plated T2Y2 copper plate, the shell is made of high temperature resistant and flame retardant PA66, the contacts are made of AgC5 silver graphite, and all the functional parts of the circuit breaker are made of the best materials.
