DCI can supply you with industrial knife switches for most any project.
The electrical rating of the switches range from 30 Amperes at 250 Volts AC/DC to 6000 Amperes at 600 Volts AC/DC.
All of these standard switches carry the Underwriters Laboratories listing. Models are available from single pole single throw to panels with multiple switches and multiple pole switches.
Open knife switches are used as disconnect switches mounted on switchboards, distribution and control panelboards.
Extensive uses of knife switches are found in the heavy industries and laboratories, for control and test panels, where visible disconnects are required.
