【英文介绍】

The REF620 IEC Feeder Protection and Measurement and control device is a dedicated feeder protection device specifically designed to protect, control, measure and monitor public and industrial power grids, including radiant, ring and mesh power grids. The REF620 provides feeder overcurrent and ground fault protection, which can be applied to neutral ungrounded networks and resistance or impedance neutral ground networks. In addition, the REF620 can also be used for ring mesh distribution networks or radiation network protection, using the device's advanced interstation communication capabilities.

The REF620 IEC feeder protection and measurement and control devices are available in single and dual bus configurations, with one or two circuit breakers and multiple switchgear configurations available for each bus configuration. The device supports a large number of manual and electric isolation switches and ground switches. The amount of available I/O can be increased according to the needs of ABB's RIO600 remote I/O devices.
