The IDD-VCR Recloser is used as an automatic sectioning point and local backup points in networks with multiple power sources in projects aimed at improving the reliability of consumer power supply.

The IDD-VCR Vacuum Recloser is a modern solution for the automation and protection of electrical networks. This vacuum recloser is designed for reliable and efficient management of medium-voltage distribution networks. The recloser is equipped with an advanced control and monitoring system, ensuring high operational reliability even under the most challenging conditions.

The device operates without reconfiguration in radial, open, closed-looped ring networks, and ring networks with dual power supply, featuring automatic or manual power supply restoration. The IDD-VCR Recloser blocks the start of overcurrent protection stages in the presence of inrush current from power transformer magnetization. The operating characteristics of automatic relay protection functions comply with ANSI-50 and ANSI-51 standards.
