Original product description
The FN18 and FN18-DR series indoor compressed-air, high-voltage load switch and fuse combination is a new modular, three-pole load interrupter switch. It is designed to provide switchgear owners and assemblers with advanced interrupting technology and reliable performance in a compact design.
The load switch is suitable for three-phase distribution systems with AC 50HZ, rated voltage12- 24KV and rated current 630A and below, used for load control and short-circuit protection.
It can quickly and reliably switch on and off load current, closed-loop current, no-load transformer and cable charging current, and has functions such as overcurrent and short circuit protection, fuse tripping and automatic tripping.
Especially suitable for ring network power supply in urban network construction and renovation projects, high-rise buildings, and public facilities, it is an ideal product for box type substations and transformer protection. Outline Drawing Product Parameters No.
