Allen-Bradley Bulletin 1494U visible-blade disconnect switch

Rockwell Automation has announced a universal visible-blade disconnect switch with global ratings of UL, CSA, CE and CCC. The Allen-Bradley Bulletin 1494U visible-blade disconnect switch is designed for applications with switched currents up to 30, 60 and 100 A. A 600 A version will also be available in 2015.

The visible-blade disconnect switch provides visible confirmation that the switch is in the ‘on’ or ‘off’ position as it isolates motors, motor controllers and other loads from a supply circuit.

The switch covers all applications, thereby reducing needed inventory. Users can choose from a number of styles and options to meet their specific application needs, including non-fusible or fusible versions, and the fusible version provides short-circuit protection. The switch can also be connected for rod or cable operation. With the cable option, users also have the flexibility to mount the switch anywhere in the panel, regardless of the handle’s location.

The disconnect switch saves users panel space with a 30% smaller footprint than previous models. In addition, the company says the switch, mechanism and multitap lugs together have a footprint that is almost 50% smaller than the footprint of previous combinations.

Aluminium lugs are standard on the universal disconnect switches, and accept copper and aluminium wiring for easier installation. Fuse clips are pre-installed for the fusible styles. With the multiport lug connector, users no longer have to wire through a distribution block and can instead connect wires directly to the disconnect switch.
