Universal Visible-Blade Disconnect Switch
UL, CSA, CE and CCC for Worldwide Applications up to 600 Amps
The Allen-Bradley® 1494 universal visible-blade disconnect switch provides customers the extra level of visual ON or OFF indication of a knife-blade disconnect design. This disconnect switch addresses needs across industries that have a global customer base by providing UL, CSA, CE and CCC ratings in a single product line.
End users can choose from a number of styles and options to meet their specific application needs, including non-fusible or fusible versions. The universal disconnect switches are unique in that they can be connected for rod or cable operation in the field. With the cable option, users also have the flexibility to mount the switch anywhere in the panel, regardless of handle location.
Panel builders may take advantage of our accessories to drive added safety and convenience. And, our unique system level design means NFPA 79 compliance is maintained with both open and closed panel doors.
