Part of the Efacec’s 220 IED family for distribution automation, protection and control, the RCU 220 is a recloser/sectionalizer controller that targets protection and control of distribution assets together with conventional RTU-functionality.

The RCU 220 provides not only reclosing function, but also feeder isolation and restoration algorithms for loop/ring configurations. The automatic loop restoration control function has the advantage of not requiring communication capabilities to isolate faulty sections and restore power to unaffected segments.

Unlike other solutions, the RCU 220 also provides open IEC 61131-3 programming and full IEC 61850 communication capabilities enabling fast and selective distributed peer-to-peer schemes, integration with centralized feeder control and monitoring systems, adaptive schemes for variable power flows or innovative plug-and-play/engineering approaches.

It’s a cost-effective solution, carefully designed for integration with multiple recloser/interrupter vendors, easy installation and straightforward configuration and management. The equipment is available with several ordering options from a standalone unit to a fully enclosed in RCU 220E cabinets that include all necessary components for recloser application.
