Siemens SIPROTEC 5 Compact 7SX800 Universal Protection Relay

Siemens SIPROTEC 5 Compact 7SX800 Universal Protection Relay Suppliers,Exporters in India

ARP IMPEX is a supplier and exporter of Siemens SIPROTEC 5 Compact 7SX800 Universal Protection Relays in India. We handle requirements for medium-voltage switchgear, feeder protection panels, industrial substations, motor protection, retrofit projects and replacement of existing numerical relays.

The Siemens 7SX800 is a compact multifunction protection relay used for feeders, distribution lines and small to medium-sized motors. It combines protection, circuit-breaker control, measurements, event recording and communication within one device.

The relay can be configured for different applications instead of using separate relay models for every protection requirement. Depending on the ordered function package, the 7SX800 can provide directional and non-directional overcurrent protection, earth-fault protection, motor protection, voltage and frequency protection, automatic reclosing and backup protection.

Its compact construction makes it useful for switchgear panels where available mounting space is limited. Different versions are available with varying binary inputs, output contacts and communication interfaces. Relay settings and engineering are carried out through Siemens DIGSI 5 software.

The 7SX800 can also communicate with SCADA and substation automation systems through serial or Ethernet interfaces. IEC 61850 is available on applicable configurations for projects requiring modern substation communication.

ARP IMPEX supplies Siemens SIPROTEC 5 Compact 7SX800 Relays for feeder protection, motor protection and medium-voltage switchgear applications. Share the complete Siemens article number for price and availability.
