Earth Fault Relay By Control & Switchgear Company Ltd.

Now efficient, Over-current, Short-Circuit and Earth Fault Relay
This new range features

* Micro controller based Numeric Relay
* Digital filtering of the measured values to suppress the high
frequency harmonics and transient dc components during short
circuit.
* Selectable protective functions between: definite time
over-current relay selectable inverse time characteristics
according to BS142 and IEC 255-4:
o Normal inverse3.0
o Normal inverse1.3
o Normal inverse0.6 very inverse extremely inverse
* Two stage over-current time protection for phase current/earth fault current
* Separately selectable characteristics for Earth fault
* Continuous self-supervision of software and hardware
* Wide operating ranges of the supply voltage [AC/DC] 24V-270V
AC/DC Last three faults recording
* Relay assignment configurable from HMI
* Relay reset configurable from HMI
* Self supervision output contact
* In standard 96x96 DIN standard enclosure
