Product Details

Introduction

The air insulated type switch disconnectors(Load Break Switches) of FN18 areintended for indoor installation in air-insulated switchgear systems. With switching,disconnecting and protection (Combinated with Fuses) for medium voltage network such asdistribution transformer, motors, capacitor banks, etc.

The LBS type FN18 is based on a modular principle. The basic unit consists of a framewith insulators and current carrying parts. Two different types of operating mechanisms.snap action mechanism type K or stored spring energy mechanism type A, can be mounted onthe frame. Fuse bases type F, with or without fuse tripping mechanism, and an earthing switchtype E/EB, suitable for both direct mounting and free standing components, complete thebasic equipment of a switch disconnector. These modules can be easily configured accordingto customer expectations. Accessories, such as shunt trip, under-voltage release, auxiliaryswitches, motor operation and various systems for manual operation can easily be added.
