Class 14 industrial magnetic starters are designed for across the line starting of single phase and polyphase motors.
Across the line or full voltage starting is used when motor starting torque can be applied safely and current inrush does not produce an objectional voltage drop. All starters are supplied with a NO holding interlock that in conjunction with an appropriate pilot device will provide low voltage protection or release.
ESP200™ starters (14*U models only; 14*S models provide ESP100 overloads) combine the rugged NEMA contactors with a state of the art solid state overload that provides phase loss, phase unbalance ground fault protection. It offers the user greater motor protection and extended life in heavy duty applications. The ESP200™ ultimately results in a cost savings to the user.
