4xI, non-directional
The 7SR210 series of relays provide overcurrent and earth fault protection. These relays are typically applied to provide the main protection on feeders and interconnectors and the back-up protection on items of plant such as transbers, Relays have four current bs and are housed in E6 or E8 cases.
7SR220 series relays include for directional control of the overcurrent and earth fault functionality and are typically installed where fault current can flow in either direction i.e. on interconnected systems. Relays have five current and four voltage bs they are housed in E6 or E8 cases.
Integrated logic is provided to allow the optimal configuration of relay functionality with the relays analogue bs and binary b/output circuits. The optional auto-reclose feature offers an integrated solution for use on OHL feeders. The relay functionality allows highly flexible settings for current and time grading making it compatible with all types of overcurrent protections.
Protection, instrumentation and metering functionality is accessible via data comms channel(s). A front USB port for local PC connection and rear electrical RS485 port for remote connection are provided as standard, additional ports are available as options.
