Best Siemens 7SR17 Relay Suppliers

The Siemens Reyrolle 7sr17 relay is a numerical protection relay they are provided with four current inputs and optionally three voltage inputs. These devices provide protection, monitoring, instrumentation, control and metering with integrated input and output logic. They also have other functionality like data logging and fault reports. The device is generally applied to motors and their connections providing an integrated protection system. They are used as stand alone devices but are capable to be supplied with an external unit to interface with remote temperature detectors ingrained in the motor or installed on auxiliary equipment. Get Reliable products as Reliserv Solution is one of the best Siemens 7SR17 Relay Suppliers in India.

Siemens Reyrolle relay has thermal protection optimized for all motor applications with motor starting supervision algorithms. These relays are multifunctional devices and also provide other protections and are selectable as required so that a smooth installation can be achieved without any error. The relay is capable of providing both current and voltage-based motor protection algorithms for various industrial motor feeder applications thanks to its draw out enclosure, higher RTD inputs enhanced BI/Os and multiple communication interfaces including IEC 61850. Siemens Reyrolle motor protection relay provides optimal protection platforms for all types of panel builders providing industrial and distribution applications. Siemens 7sr17 relay is provided in an E4 case its user-configurable with integrated logic that enables the optimal configuration of relay input and output functionality.

These devices have an expansive protection function package with reliable hardware design as standard with options for increased binary inputs & outputs, voltage inputs, and IEC61850 communications.
