Benefits

High Performance

The unique 2-pole switch design has been optimized to break mid-currents up to 1500V DC easily and reliably, across the complete lifespan of the installation

Fast and Flexible

Modular design provides the advantage of operating more than one 1500V DC circuit simultaneously with a single switch, giving you more alternatives to design your installation

Energy Efficient

Design has been optimized for a smaller footprint and high performance. A compact size gives you the possibility to use a smaller enclosure, without worrying about power losses

Features

Double contacts, totally isolated in the OFF position
Switches can be side or front operated and mounted in any direction without significant impact on the performance
Aux Contacts, Terminal Shrouds, CSA mechanical lugs, neutral available as accessories
Pistol and selector handles, plastic and stainless steel handles available as accessories
Other premium configurations available including: Multiple poles (2p,3p, 4p,6p)
