1. Product Description
        FT8 - 12 (24)Type indoor AC high voltage load switch and within FT8 -12 R / 125-31.5 type indoor AC vacuum load switch - fuse combination is my factory to meet user needs from its own research and development. Performance to GB3804 "3 ~ 63KV AC high voltage load switch" and GB16926-97 "AC high voltage load switch - fuse combinations" international standards.
        Products with chain simple and reliable, compact structure, when the cabinet with safe, reliable, lower volume, beautiful appearance, stable performance, safe and reliable breaking, frequent operation and other advantages, it also has a dual-manual and electric operating functions and operations easy and intuitive, low operating force, to prevent misuse and more reliable. Load switch - fuse combination also protects Transformer overload, prevent equipment missing running function.

3. Structure Introduction
        In the distribution cabinet design, make the room above and below the bus cable compartment through a grounded metal undercarriage divided into two compartment, so after opening above the disconnecting switch, to ensure the safety inspection when the cable compartment.
        Having dual manual and electric operating functions and operating a small force.
        Mis interlock integrated actuator box, simple and reliable.
        Small size, light weight, compact structure.
        Vacuum interrupter placed in the insulating sleeve, greatly reducing the dust accumulate on the surface of the interrupter, the interrupter can also prevent the impact of various external factors.
        Vacuum interrupter using side-mounted, reasonable and novel structure, beautiful appearance.
Hotels cabinet easy to install.
