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.
Accurate Earth Leakage ProtectionThe ELR96-1C is specifically crafted to detect and act upon earth leakage faults, thereby enhancing safety in electrical systems. Its adjustable current range from 0.5A to 5.0A allows it to be tailored for a wide variety of applications, providing essential protection for both people and equipment.
Convenient Operation and Reset OptionsWith both manual and auto reset modes, users can select how the device responds after a fault. LED indicators deliver easy recognition of operational and trip conditions, streamlining maintenance and ensuring quick fault identification.
Flexible Mounting and Durable DesignEngineered for flush or panel mounting, the miniature-sized relay features a flame retardant ABS case for superior safety. Its solid-state design eliminates the need for coil voltage, contributing to its long operational life and high reliability.
FAQ's of Earth Leakage Relays ELR96-1C E:0.5A-5.0A:
Q: How does the ELR96-1C detect earth leakage or faults in electrical circuits?
A: The ELR96-1C monitors the current flow and senses leakage currents between 0.5A and 5.0A, responding when a preset threshold is exceeded. This enables prompt disconnection or alarm in case of earth leakage, enhancing safety.
Q: What is the process for setting the current sensitivity on the ELR96-1C?
A: You can adjust the current setting range between 0.5A and 5.0A using the front controls. This allows you to tailor protection based on your system's requirements, ensuring accurate detection of earth leakage conditions.
Q: When should I use the manual or auto reset feature?
A: The manual reset is recommended when direct intervention is needed after a fault, ensuring faults are acknowledged. The auto reset is suitable for applications where automatic restoration of power is desired after transient or cleared faults.
Q: Where can the ELR96-1C be installed in an electrical system?
A: It is suitable for flush or panel mounting, making it versatile for switchboards, control panels, or distribution boards in industrial and commercial electrical systems.
Q: What are the benefits of the ELR96-1C's LED indication system?
A: The LED indicators clearly display the relay's operating status and trip condition, ensuring quick and straightforward fault diagnosis, which reduces downtime and facilitates maintenance.
Q: How does the relay ensure operational reliability and safety?
A: Constructed with a flame-retardant ABS case and a solid-state design, the relay offers a high mechanical life (>1 million operations), insulation resistance over 100M, and adheres to IS/IEC 60255 standards, ensuring consistent, safe operation.
Q: What power supply options are available for the ELR96-1C model?
A: The relay is available for either 230V AC or 110V AC operation. Specify the required voltage at the time of ordering to match your system's supply requirements.
