The SB-400-60RS is a rugged lightweight motor controller used primarily to control wall saws and slab saw motors.
It has both a voltmeter and amp meter so the operator can run the motor at it’s maximum efficiency.
The input and output plugs are 50 Amp Hubbell style on short cords and is the reason for being called a “Special Switchbox”.
Additional output plugs, available with or without controlling switches can be added to the switchbox for convenience.
It has a rotary reversing switch to quickly change the rotation direction of the diamond tool. Convenient rear mounted hooks are provided for hanging this switchbox from a ladder or other locations.
