Fn12-12rd Indoor Use Air-Compressing High-Voltage Switchgear with Fuse
Basic Info
Model No.: FN12-12RD/125-31.5
Product Description
Model NO.: FN12-12RD/125-31.5 Usage: Control Switch Number of Switch: Multi Control Switch Arc-Extinguishing Principle: Air-Compresing Type: Indoor High Voltage Trademark: YF Function: Industry, Circuit-Breaker Failure Protection Pole: 3 Certification: SGS, ISO9001, CE Test Equipment: IEC Standard Operation Model: Manual or Electric Operation Origin: Jiangyin Yunfeng, China Product Overview
YFN12(FN12)-12 series indoor AC HV load switch works under the air-compressing arc extinction principle. Because of its unique structural design, it can make full use of the air-compression extinguishing arc generated in the trippingprocess of switch. Its performance meeets the requirements of national standards GB 3804-2004 High-voltage alternating-current switches for rated voltage above 3.6kV and less than 40.5kV and GB 16926-2009 High-voltage alternating current switch-Fuse combinations.It is applied in the HV AC 12kV network with the frequency of 50HZ for opening, closing the load current, overload current and making the short-circuit current. Together with the HV current-limiting fuse and trip device, it combines YFN12-12R series indoor AC HV load switch-fuse combination unit, which can reliably disconnect the
rated short-circuit current.
