Quick Overview

Deformation of Busbar during Operation without need of Flexible connexion
No Load operation
Indoor Type - Horinzontal axis mounting only offering very compact design
Configuration with 1 pole. Upon request, two poles or change-over design by side association of two disconnectors
Mechanical endurance 1000 cycles (with respect to maintenance instructions)
Connexion plates in Aluminium
Large customization possible with :
- connexion plate (length, fixing holes)
- Manual, motor or pneumatic drives
- auxilaries switches, blocking magnets, locking devices
- dimension fitting
Typical temperature rise at nominal current 15°K above busbar (with 40°Cmax.)
Temperature rise at nominal current is less than 65°K (with 40°C max. ambient temperature)
Visible break by direct seeing of the mobile silver-plated copper contacts
All contacts are fitted with solid silver, high temperature brazed (special process)
Connections to busbar by welding and self-supporting (Busbar must be sized to withstand the disconnector additionnal weight)
Electrical contact with silver to silver contact which offer high short-circuit current withstand and Low and constant voltage drop
Large insulation and creepage distances using Fiberglass reiforced polyester insulators
Ponctual temperature withstand without equipment damages 140°C
Upon request, two poles or change-over design by side association of two disconnectors
