    The Reyrolle 7SR17 Rho is a numeric protection relay with four current inputs and optionally three voltage inputs.

    The relay is applied to motors and their connections providing an integrated protection system.

    The relay is typically used as a stand-alone device but can be supplied with an external unit to interface with remote temperature detectors embedded in the motor or installed on auxiliary equipment.

    The Reyrolle 7SR17 Rho relay includes thermal protection optimised for motor applications and motor starting supervision algorithms. Several other protections are also provided and are selectable as required so that a solution appropriate to the installation can be achieved.

    The Reyrolle 7SR17 Rho is housed in an E4 case.

    Full user configurability and integrate logic allows the optimal configuration of relay input and output functionality.
