Reliable performance and stable quality
KYb3-63 SERIES MCB products comply fully with IEC 60898-1.The internal conductive parts of the product are all made ofsilver-plated T2Y2 copper, the outer shell is made of heat-resistant and flame-retardant PA66, and the contacts are made of AgC5 silver graphite.Kyb3-63 products have reliable performance, exquisite production technology and good quality consistency.
Advanced design, simple structure
The KYB3-63 series circuit breakers are integrated with a number of patented technologies, among which the integrated coil design, multi-function magnetic yoke design, multi-arc channel arc extinguishing chamber and so on are all industry-first designs.We have made a radical optimization of the internal structure of the circuit breaker.The internal structure of the KYB3-63 series circuit breakers has been greatly streamlined through a series of original and advanced designs while ensuring product performance.The number of parts of the product is only 30, which is 15 fewer parts than the conventional miniature circuit breaker products.The product has only 3 welding spots, 5 less than the conventional product.Every time you remove a part, you remove a factor that affects the consistency of the product.Each reduced solder joint reduces the risk of production quality and also improves the production efficiency of the product.Therefore, KYB3-63 series circuit breaker is a high quality circuit breaker with high reliability and quality stability.
Good quality and cheap price
Through various optimization design of the circuit breaker, our circuit breaker has the following characteristics:
1. The number of parts of the product is reduced, which is 15 parts less than conventional circuit breakers.The reduction of the number of parts not only reduces the material cost of the product, but also greatly improves the assembly speed and production efficiency of the product.
2. The welding points of circuit breaker are reduced from 8 to 3, and the riveting points are reduced from 4 to 1.The reduction of welding points and riveting points not only reduces the quality risk of the product, but also improves the production efficiency and reduces the production cost.
3. Improved copper utilization rate of circuit breaker products.With the reduction of welding points and the optimization of
structure, the copper material utilization rate of the product is improved, thus reducing the use amount of copper material for circuit breaker and reducing the material cost of the product.
Through the above multi-channel optimization design, the material cost and production cost of KYB3-63 series circuit breakers have been greatly reduced, so the price of KYB3-63 series circuit breakers is very competitive.Of course, our circuit breaker products are through the advanced design to reduce the cost of the product, this cost reduction is based on the performance of the product, and some manufacturers in the market through cutting corners, sacrifice product quality to reduce the cost of the product approach is fundamentally different.
