Features:

True RMS measurement.
Clearance & creepage distance meet UL61010 safety standard.
Inverse curve-trip time is inversely proportional to fault current. This ELR is intelligent, when the leakage current is 10 times higher than the set current. It trips 10 times faster.
Field programmable trip current and trip time through front panel keys with password protection.
Continuous leakage current display programmable to enhance the user to understand the quality of electrical network/machine 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 trip current with 4-digit resolution which helps the user to analyze and rectify the problem. This can be disabled through setup if required.
Continuous scrolling of display for set current and set time.
Wide I/P range: 300mA to 12A and trip time: 300ms to 30 sec. programmable. Option of 30mA to 1A available.
Manual test and reset keys.
RS485 communication option.
