Schneider Sepam M61 PowerLogic Motor Protection Relay Suppliers, Exporters in India

Schneider Sepam M61 PowerLogic Motor Protection Relay is a numerical relay designed to protect and monitor medium-voltage motors used in industrial power systems. It combines motor protection, measurement, control, and monitoring functions in a single device, helping improve motor reliability and reduce unplanned downtime.

The Sepam M61 is developed for applications where motors operate under varying loads or demanding conditions. It provides protection against overloads, phase faults, earth faults, locked rotor conditions, excessive starting time, and thermal stress. The relay also offers electrical measurements, event recording, and circuit breaker supervision, making fault diagnosis and maintenance easier.

Widely used in industrial plants, utilities, and infrastructure projects, the Sepam M61 remains a dependable solution for protecting critical motors. Although it is part of a legacy product family, it continues to be installed in many facilities and is commonly required for replacement and retrofit projects.

Note: The Sepam M61 is part of the Schneider Sepam Series 60 numerical protection relay family and is widely used in existing medium-voltage motor protection applications.
