General Information
- Manufacturer: ABB
- Model/Part Number: REF610C55HCNR
- Model Type: Feeder Protection Relay
- Description: The ABB REF610C55HCNR is a feeder protection relay from ABB's Relion 610 series, designed for the protection, control, and monitoring of incoming and outgoing feeders in medium-voltage distribution substations. It provides overcurrent, earth-fault, and thermal overload protection, making it suitable for both utility and industrial power systems with resistance-earthed or solidly earthed configurations. The relay supports advanced communication protocols and is ideal for applications requiring reliable fault detection and minimal downtime.
