Electrical High Efficiency Reyrolle 7sr110 And 7sr120 Automotive Argus Relays

Paying due attention to existing market demand, we are engaged as trader, supplier, and exporter of Reyrolle 7SR110 And 7SR120 Argus Relays in Navi Mumbai, Maharashtra, India.

The 7SR11 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 backup protection on items of plant such as transformers. On distribution system circuits overcurrent and earth fault protection is often the only protection installed.

The 7SR12 includes directional control of the overcurrent and earth fault functionality and is typically installed where fault current can flow in either direction i.e. on interconnected systems.

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 or rear electrical RS485 port for remote connection is provided.
