Schneider Electric PowerLogic™ P7 Motor Protection Relay

The Schneider Electric PowerLogic™ P7 Motor Protection Relay is designed to protect and monitor medium and high-voltage motors used in industrial plants, utilities and critical process applications. It combines comprehensive motor protection, control, condition monitoring and communication functions in a single intelligent device, helping improve equipment reliability and reduce unexpected downtime.

The relay continuously monitors motor operating conditions and responds quickly to electrical faults, overloads and abnormal operating situations before they cause damage. It supports a wide range of motor starting methods and can be configured for induction and synchronous motors used in demanding industrial environments.

Built on the PowerLogic P7 platform, the relay supports IEC 61850 communication, programmable automation and advanced cybersecurity. Its flexible configuration, real-time diagnostics and graphical user interface simplify commissioning, maintenance and integration with modern SCADA and substation automation systems.
