Directional Idmt Relay Self Powered
The Vishw Automation Directional IDMT Relay Self Powered is a protective relay designed for three-phase power systems, specifically to detect and isolate fault currents flowing in a reverse direction. It operates without external power supply, drawing energy from the monitored current circuit, and is rated for 5 A secondary current with a setting range of 0.5 to 2 A. The relay is configured for 50 Hz systems and operates on 63.5 to 190 V AC.
This relay uses an induction disc mechanism with inverse-time characteristics, meaning tripping time decreases as fault current increases. It has a case size of 1.5D S/E, indicating a standard industrial footprint. The relay includes three normally open (N/O) contacts for tripping, two additional N/O contacts for alarm signaling, and a mechanical flag to indicate operation. It complies with the ALSTOM GBCDD21PF004SBCH model specification.
This relay is used in medium-voltage distribution networks, particularly in ring main units and dual-source feeders where directional overcurrent protection is required. Buyers include utility companies, industrial plant operators, and electrical contractors in regions with radial or meshed grids. The relay is supplied as a standalone unit; mounting hardware and wiring diagrams are provided with the product. No lead time or MOQ is stated in the listing.

Sourcing Directional Idmt Relay Self Powered from Vishw Automation - India Import Guide
Before ordering, confirm the relay's current setting range, voltage range, and burden match your CT and system parameters. Request the time-current curve for coordination studies. Verify that the relay is compatible with your existing control panel and that the 1.5D S/E case size fits your mounting space. Do not assume it is a direct replacement without physical and electrical verification.
Lead time, Incoterms, and payment terms are not provided and must be confirmed with the supplier. Common terms for Indian exports include FOB Mundra Port or CIF destination. Payment is typically via T/T in advance or LC. Ask for a sample unit to validate wiring diagram MPDZ801.23 and outline drawing MFJ 013 before bulk purchase.
For quality assurance, request a sample for functional testing under simulated fault conditions. Check that the directional element operates only under reverse current and that the flag resets manually. Inspect the case for proper sealing and label legibility. Retain test reports and calibration certificates for compliance with IEC 60255 standards.
