CFU-4A6 Combination Fuse Units / Switch Disconnector Fuse Units have been designed to comply with the requirements of AC-23 Utilization Category according to IEC 60947 / IS 13947. The Combination Fuse Units are suitable for switching operations from no-load condition to highly inductive loads
Switch Disconnector Fuse Unit CFU-4A6 Combination Fuse Units / Switch Disconnector Fuse Units have been designed to comply with the requirements of AC-23 Utilization Category according to IEC 60947 / IS 13947. The Combination Fuse Units are suitable for switching operations from no-load condition to highly inductive loads Features: The CFU-4A6 is the only Fuse Combination Units fuse switch originally designed for 4-Pole operation, with a break neutral for total isolation. The 3-Pole and 3-Pole with solid neutral versions are also available. CFU is suitable for mounting in horizontal or vertical position. Compact dimensions result in valuable in space saving results. CFU are front operated with door interlocking with defeat arrangement as standard features CFU-4A6 uses Sheet Moulding Compound (SMC) as the main insulating as well as structure material for superior performance and longer life. Unique contact and mechanism design ensure high short circuit making breaking and withstand capability. The CFU is fully confirmed us to AC-23 utilization category as per IEC 60947 / IS 13947 CFU has been tested for fused short circuit current of 50kA at CPRI, Bhopal. Terminals have been designed for taking on directly, aluminum cables. The terminals are easily accessible The fixed and moving contacts have been designed for heavy duty application at the same time, both fixed and moving contacts are replaceable. Stationary fuse design ensures lower mechanical shocks to the system as well as an ability to withstand a high level of electro-dynamic shocks. Auxiliary Contact upto 2 No + 2 NC optional
