Product Description
The relay senses the Earth leakage current for any equipments like L. T. Panels, Switch boards, Generators, Transformers, Motors etc. These Leakage current if continues can cause insulation breakdown resulting Earth fault, which results in to loss of life or damage to equipment. The PROTIME Earth leakage relay senses leakage current through CBCT & energies relay when current goes out of the range selected on the dip switches. The Relays are provided with user settable (0-10 Sec) time delay. The CBCT is connected externally with the Busbar or cable carrying load current passed through it. The Relay has facility to show fault current indication on pressing STATUS Button. Thus this feature helps user to identify the point of fault & find out the value of fault current passing through it.

FAQ's of Earth Leakage Relays ELR96-1C/i E:0.5A-5.0A:
Q: How does the ELR96-1C/i detect earth leakage currents?
A: The relay utilizes an electromagnetic relay detection principle to sense earth leakage currents within the adjustable range of 0.5A to 5.0A. When a current exceeding the set threshold is detected, the unit trips the output relay to disconnect the circuit, thereby providing quick and reliable protection.
Q: What is the process for resetting the relay after a trip event?
A: The ELR96-1C/i can be reset manually using the front panel reset function or automatically, depending on the selected mode. This flexibility allows users to choose the preferred reset method based on safety procedures and operational requirements.
Q: When should the push-button test facility be used?
A: The push-button test should be used periodically during scheduled maintenance or installation checks. Activating this function simulates a leakage event, enabling users to verify the correct operation of the relay's detection and trip mechanism without introducing a real fault.
Q: Where is this earth leakage relay typically installed?
A: Designed for panel (flush) mounting, the ELR96-1C/i is suitable for switchboards, distribution boards, and motor control centers in industrial plants, commercial complexes, and residential setups needing reliable earth leakage protection.
Q: What are the benefits of using LED indication for status and fault?
A: The built-in LED indicators provide clear and immediate visual feedback of the relay's operational state and any detected faults, making status monitoring straightforward and enhancing safety by supporting rapid troubleshooting.
Q: How does the adjustable operate time enhance protection?
A: Allowing users to set the operate time from 100ms to 1s helps optimize protection for different applications by minimizing nuisance tripping during transient conditions while ensuring faults are isolated quickly for maximum safety.
Q: What standards does the ELR96-1C/i comply with, and why is this important?
A: The relay meets IS/IEC 60947-1 and IS 12640-1 standards, ensuring conformity to internationally recognized safety and performance criteria. This compliance guarantees dependable operation and facilitates acceptance in regulated markets and critical installations.
