The vertical bar fuses switch disconnector come in 2 models, according to the disconnecting type:
– independent monopolar division/break (EHL/S)
– simultaneous tripolar division/break (EHL/L)
All disconnectors use cartridge fuses MPR type. They are manually operated. Closing or opening must be executed with a firm and continuous movement of the handle. The length of the devices is 50mm for size “00” and of 100mm for sizes “1”, “2” and “3”.
The disconnectors can be mounted also on distribution bars systems which have a distance of 185mm between bars centers.
The base is made of glass fiber strengthened polyester, self extinguishing. The contacts are silvered, which minimize the losses caused by Joule effect.
The disconnectors can be equipped with terminal blocks which allow connecting the cable with or without lugs.
The case that covers the contactes has extinguishing rooms and its made of reinforced polyamide with glass fiber.
The vertical bar fuses switch disconnectors facilitate the usage of power transformers and ammeters. The adapters that came with it allow their mounting on different types of distribution bars. The protection degree provided is IP20.
All devices come with fixing terminals type V and cap for terminals.
