Protection

Motor protection safeguards the motor, the electrical supply system and personnel from various hazardous operating conditions. These hazards can come from the driven load, the electrical supply system or the motor itself. The time to consider protective devices and other controls is during the selection process. Overloads, short circuits, low voltage, and other hazards can damage motor windings, electrical conductors, or burn out the motor itself. This is why motor protection is a vital aspect of planning and operation.
