GMK0-IF

Model GMK Motor Protection Switch is a three-pole horsepower rated switch which combines motor thermal overload protection and magnetic short circuit protection in one compact unit. Incorporates a manual disconnect switch and instantaneous magnetic trip mechanism in one compact device. The GMK is ideal for applications requiring multi-motor operation. UL permits Group Fusing for motors up to 10 amperes full load current. This provides the option for grouping a number of motors under one branch circuit disconnect and fuse set. This saves panel space and additional component cost. Remote control operation and low voltage protection can be provided by adding a Type “JM” Contactor in series with the motor protection switch.
