Directional control
7SR220 relays come with five current and four voltage inputs, in E6 or E8 cases. This makes them ideal for installation on interconnected systems with bidirectional fault current.
Why Reyrolle 7SR220?
The Reyrolle 7SR220 series relays provide directional overcurrent and earth fault protection. Install these relays on interconnected systems where fault current can flow in multiple directions for robust protection. Safeguard your system from damage, limiting potential downtime.
