Buy Schneider Sepam Series 80 PowerLogic Numerical Protection Relays Suppliers, Exporters in India
Schneider Sepam Series 80 PowerLogic Numerical Protection Relays are advanced digital protection relays developed for current and voltage protection in medium-voltage distribution networks. The series combines protection, measurement, control, monitoring, and communication functions in a single device, making it suitable for a wide range of industrial and utility applications.
Sepam Series 80 offers dedicated relay models for feeders, transformers, motors, generators, busbars, and capacitor banks. Each relay is designed for a specific application, allowing engineers to select the most suitable protection scheme without adding unnecessary functions. The relays also provide detailed measurements, event recording, fault analysis, and communication capabilities to simplify system monitoring and maintenance.
With support for modern communication protocols and integration into substation automation systems, the Sepam Series 80 remains a widely used solution for power distribution. Although this is considered a legacy product family, it is still installed across many industrial plants, utilities, and infrastructure projects, making it a popular choice for replacement and retrofit requirements.
Note: Sepam Series 80 is a legacy Schneider Electric protection relay family. It continues to be widely used in existing installations, while newer projects may use the PowerLogic P3 or PowerLogic P5 protection relay range depending on the application.
