Class 1 protection for power supply?

The digital, solid-state CDP series is adjustable for Class 1 through Class 60.

The wide range of class adjustments with the Model CDP will allow the relay

to be adjusted for the maximum protection of the motor. Thus, if a motor is

normally up to running speed in six seconds then the overload relay may be

adjusted for Class 1 with a nominal trip time of 12 seconds at 125% overload.
