KFW5 Series
Air Circuit Breakers
KFW5 Series represents a new generation of air circuit breakers developed by Jiangsu Daqo KFINE Switch Co., Ltd. Designed for large-current low-voltage power distribution, it serves industrial facilities, commercial buildings, metallurgy, chemical industry, and power plants. It delivers comprehensive protection against overload, short circuit, earth fault, and voltage irregularities. Available in four frame sizes (1600A, 2500A, 4000A, and 7500A) with rated currents from 200A to 7500A, the series supports AC 400V and 690V (50-60Hz). The product is available in 3-pole and 4-pole designs in both drawer-type and fixed-type constructions, with breaking capacity up to 150kA.
Suitable for demanding environments with high short-circuit currents, such
as large power plants and heavy industries.
Suitable for high-performance applications with high short-circuit current requirements, such as industrial production lines, critical power equipment, and heavy industry sectors.
Suitable for conventional applications with low short-circuit currents, such as residential buildings, schools, hospitals, infrastructure, and factory lighting distribution areas.
