The Reyrolle 7SR511 is a numerical overcurrent protection relay designed primarily for distribution and industrial networks. As detailed in the 7SR51 Device Manual , its core function is to safeguard electrical equipment—such as feeders, transformers, and motors—from damage caused by excessive currents, including short circuits and overloads. By monitoring current levels and triggering circuit breakers when thresholds are exceeded, the device prevents catastrophic equipment failure and maintains system stability.
