RELION® 615 SERIES PROTECTION AND CONTROL RELAYS • = Supported o = Optional add-on Application REF615 has been designed to be the main overcurrent and earth-fault protection for overhead lines and cable feeders, in either isolated neutral, resistance-earthed, compensated or effectively-earthed distribution networks, depending on the standard configuration. REF615 is available in twelve standard configurations. In addition to standard configuration N, also L now provides maximum functionality to allow fully flexible tailoring. The major difference is that L includes support for three...

Application REU615 is available in two standard configurations. One has been exclusively designed for busbar under- and overvoltage supervision, load-shedding (disconnection) and restoration (reconnection) applications. It can also be used for over- and underfrequency protection of power generators and other AC equipment such as capacitor banks. In generator and motor applications, REU615 provides • = Supported o = Optional add-on Product highlights • Extensive range of protection and control functionality for busbar voltage supervision, load-shedding and restoration, including over- and...

RELION® 615 SERIES PROTECTION AND CONTROL RELAYS Application REM615 has been designed to be the main protection for asynchronous motors and their drives in manufacturing and process industry. Typically, the motor relay is used with circuit-breaker and contactor-controlled MV motors and medium-sized and large contactor-controlled LV motors in a variety of drives. The drives include both continuously and intermittently operated asynchronous motor drives with varying load, such as pumps and conveyors, crushers and choppers, mixers and agitators, fans and aerators. REM615 is available in four...

Application REV615 has been designed to be the main protection for H-bridge, double Y and single Y-connected capacitor banks and feeder cables. Additionally, REV615 can be used to protect harmonic filter circuits when no significant harmonic component is higher than the 11th. REV615 is available in two standard configurations, both of which offer three-phase overload protection, current-based unbalance protection with compensation for natural unbalance, and current-based switching resonance protection for capacitor banks. The overload protection includes an integrated undercurrent function...
