Its advanced sensing technology, complemented by selectable current settings, ensures tailored protection for varied electrical installations, improving safety levels in distribution and control panels.

User-Friendly Operation and Maintenance

With flush mounting for seamless panel integration, this relay includes clearly marked FAULT and HEALTH LEDs, as well as accessible TEST and RESET buttons on the front panel. These features make routine checks, testing, and fault resetting straightforward, reducing downtime and enhancing operational efficiency.

Built for Safety and Compliance

Complying with IS/IEC 60255 standards, the device is housed in a robust ABS flame-retardant plastic enclosure, safeguarding against electrical and fire risks. A dielectric strength of 2kV, high insulation resistance, and a mechanical life over 10,000,000 operations reflect its commitment to safety and long service life.

FAQ's of Earth Fault Relays EFR96-1C/i:

Q: How does the EFR96-1C/i Earth Fault Relay detect and respond to earth leakage faults?

A: The EFR96-1C/i senses residual earth leakage currents using an advanced detection system. When the earth leakage exceeds the selected threshold (set via DIP switches), the relay operates, triggering a FAULT indication and enabling fault annunciation through the panel.

Q: What benefits do the separate FAULT and HEALTH LEDs provide?

A: The distinct FAULT and HEALTH LEDs offer clear visual status, allowing users to immediately recognize operating or fault conditions. This aids in quick troubleshooting and ensures timely response to earth fault events.

Q: How do I test or reset the relay after a fault occurs?

A: You can use the front panel TEST button to simulate an earth fault and verify the device's response. After a fault is detected and cleared, simply press the RESET button to restore the relay to normal operation mode.

Q: What current setting options are available, and how is the setting made?

A: Current sensitivity on the EFR96-1C/i can be set between 0.25A and 5A using DIP switches, allowing adaptation to specific application or protection requirements. The DIP switches are easily accessible, enabling quick adjustments on-site.

Q: Where is the EFR96-1C/i typically used, and what are its installation specifics?

A: This relay is primarily used in electrical distribution panels for earth leakage protection. It is designed for flush mounting, requiring a panel cutout of 92x92mm, with all supply and signal terminals positioned on the back for tidy integration.

Q: What safety and durability standards does the EFR96-1C/i meet?

A: Complying with IS/IEC 60255, the relay offers a flame-retardant ABS enclosure, dielectric strength of 2kV for 1 minute, high insulation resistance (100 M at 500VDC), and a mechanical life exceeding 10 million operations, ensuring lasting reliability and safety.
