About 1494V-DR644-A-D

The 1494V-DR644-A-D disconnect switch from Allen-Bradley is a variable-depth fusible disconnect switch with a continuous current rating of 400 Amps at 600 Volts AC and 250 Volts DC. Two accessories are included on the 1494V-DR644-A-D switch, and these accessories are standard-size load and line lugs and a long connecting rod. The body of the switch is made of glass-filled thermoset plastic and the terminals are made of 3/8 inch 24 screw-lug copper. Allen-Bradley recommends that the wire used for terminations on the switch must be sized according to the local electrical code and rated for 75 degrees Celsius. The recommended wire size used for terminations on the switch is 250 MCM. The recommended torque is 275 lb-in for conductor into lug and 175 lb-in for lug to terminal. The rated electrical and mechanical lives of the 1494V-DR644-A-D switch are both 6000 operations.

 

The maximum number of operations per hour that the 1494V-DR644-A-D switch can sustain is 240. The switch can sustain a maximum short circuit current of 200,000 Amps at 600 Volts AC with Class R fuses. The installation of the switch at altitudes that exceed 2000 meters should be avoided. The output power rating at 250 Volts DC is 50 Horsepower. The output power ratings at 3-phase AC input at 60 Hertz are 350 Horsepower at 575 Volts AC, 250 Horsepower at 460 Volts AC, 125 Horsepower at 230 Volts AC, and 75 Horsepower at 208 Volts AC. The fuse voltage is 250 Volts AC and the fuse clips are Type R clips. The 1494V-DR644-A-D switch is part of the Bulletin 1494V product line which is designed by Allen-Bradley for industrial applications.
