Type K motor starting switches provide manual on-off control of 1 or 3-phase AC motors, where overload protection is not required or is provided separately. These devices are suitable for use with 3-phase AC motors rated up to 20 hp. Compact construction and a 600 VAC rating make these switches suitable for a wide range of industrial and commercial uses. Typical applications include small machine tools, pumps, fans, conveyors and many other types of electrical machinery. They can also be used on non-motor loads such as resistance heaters.
