This recommended practice describes the protection of electric motors used in industrial and commercial power systems. The contents cover ac and dc motor protection including factors to consider in the protection of motors, types of protection, and low-voltage and medium-voltage motor protection, including the motor branch circuit, for fixed speed and adjustable speed drive applications. Motor protection during various operations is included, such as motor starting and motor bus transfer. Recommended protection functions are included for multifunction motor protection relays for contactor controlled starters and breaker controlled starters. Supportive diagrams are also included. Technologies for condition monitoring of motors are included. Motor protection in various environments is also included, such as hazardous (classified) locations.

IEEE Recommended Practice for Motor Protection in Industrial and Commercial Power Systems
The protection of motors used in industrial and commercial power systems is covered. It is likely to be of greatest value to the power-oriented engineer with limited experience in the area of protection and control. It can also be an aid to all engineers responsible for the electrical design of industrial and commercial power systems.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
