Description
Digital Earth Leakage Relay, 96x96mm, Panel Mount, 300mA to 30A, Class 2FS, RS485: Elmeasure iELR 300
- True RMS measurement
- Clearance and creepage distance meets UL 61010 safety standard
- Intelligent Protection – trip time is inversely proportional to fault current
- Field programmable trip current and trip time through front panel keys with password protection
- Continuous leakage current display (Programmable) – Leakage current is continuously displayed to enhance the user to understand of the quality of the Electrical network / Machine/troubleshooting online. This can be disabled through setup if required
- Continuous display of trip leakage current (Programmable) – In case of tripping, iELR captures and displays the tripped current with 4 Digits resolution, which helps the user to analyze and correct the problem. This can be disabled through setup if required
- Continuous scrolling display for set current and set time
- Manual test and reset keys l RS485 communication option
- Auto Configuration through communication
- Reset through communication in trip condition
- Protects control panels and switchboards from flame leakage
- Protects motors/transformers/feeders/generators etc., from earth leakage
- Hazardous and sensitive industries like oil refineries/pulp industries / electrical distribution etc. can be protected
- Complete protection for control engineering and mining industry
Advantages
- The microcontroller-based design provides a higher technological advantage
- Peak detection and value display help in the analysis and corrective action
- Password protection for security against mishandling
- Current sensitivity wider range 30mA – 3A and 300mA to 30A no limitations on set current (30mA to 30A coming soon)
- Programmable trip time 30ms – 30s with a wider choice to suit different industry
- Selection through soft keys (No DIP switches) provides better IP protection and longer life
- Continuous earth leakage value display helps online loss analysis (Programmable)
- Intelligent tripping based on T 1/A gives faster and more reliable protection
- Auto scrolling of trip information and peak fault current provides better analysis
