Manual Motor Starters

For Group Motor

The need for individual short-circuit protective devices such as fuses is eliminated with group motor applications; this saves both installation expense and panel space. ABB Line Manual Motor Starters are UL listed and CSA approved which can be used in group installations of motors.

For Single Motor

ABB manual motor starters provide overload protection as required by Article 430 of the National Electrical Code. Control is provided by manual operation of the contacts; overload protection is provided by an adjustable bi-metallic trip mechanism.
