Additional Details

The relay measures the line current of each of the line CTs, and if the current exceeds the set threshold, the relay extends a trip signal after a runtime. The "runtime" of the relay is determined by selecting "defined time" or one of the six "inverse time" characteristics. The input to the sensitive earth fault protection can be connected in two ways. First, the residual current derived from three phase current transformers, and the second is low output base balance current transformer can be connected. The input to the restricted earth fault protection will be derived from the neutral CT output with an external stabilizing resistor. Earth, sensitive earth, sensitive/protected earth fault overcurrents can be enabled or inhibited independently.

Features:

Programmable for a 1A / 5A relay

3 OC + 1 EF + 1 SEF / REF

Choice of 6 IDMT curves and defined time

Travel test facility

History of the last 6 faults as well as parameters

Self-supervision installation

MODBUS open protocol on the RS-485 port

MODBUS protocol via the RS-232 port

Draw an installation with an integrated CT short circuit

Standard dimension - 144mm x 144mm

Application:

The relay provides a phased phase and a ground fault (2 steps) protection with ease of communication.

With almost more than a decade of experience and rich technological expertise, we are able to offer a precision designed range of Electrical Protection Instruments.
