Introduction

The FN5-12(24) Indoor AC M.V. load switch and fuse combination is designed by ourselves, combined with the requirement of our country and based on the advanced foreign technique. It has been tested for long term by full aspects and confirmed to IEC62271 “AC M.V. load switch-fuse combinations” and GB3804 “3-63kV AC M.V. load break switch” standard. Compared to the same products of overseas, It has come up to the technique parameter level. For its small size and light weight, it can be used in RMU and compact substations, also widely used for the power distribution of the 12kV and 24kV line and has the perfect function of open phase protection. And break on-load current, over-load current and short circuit current. This Load Break Switch can apply with CS6-I manual operating mechanism. The development of the FN5-12(24) realized the functions of three-position switch: ON/OFF, isolation and grounding.
