Arc flash protection relay / panel-mount / digital / programmable
Schweitzer Engineering Laboratories
panel-mount, digital, programmable, configurable, multifunction, for electric motors
Protect asynchronous (induction) and synchronous motors with one SEL-710-5 Motor Protection Relay. New features include broken rotor bar detection and variable-frequency drive (VFD) support as well as options for arc-flash detection, differential protection, and synchronous motor protection. The synchronous option also includes, at no additional cost, a voltage divider accessory to interface with the motor excitation system.
