Variable Earth Leakage Relays in compact 35mm din rail mounting cases for use on 3 phase electrical systems.
To monitor earth leakage current and to operate an associated relay at a preset current. May be used to shut down a system or operate an alarm under fault conditions.
|Part number||Sensitivity||Time Delay||Frequency||Voltage|
|RCR-V30||30mA-30A||0-10 Seconds||50/60Hz||115/230V AC|
|RCR-V30-400V||30mA – 30A||0-10 Seconds||50/60Hz||400V AC|
|RCR-V30-60V DC||30mA – 30A||0-10 Seconds||50/60Hz||10-60V DC|
ELR’s are fitted with test and reset buttons. Pressing the test button allows a fault to be simulated and the output relays operate accordingly. Pressing the reset button after a fault occurs restores the unit back to its normal operation. A red LED light will illuminate after the unit trips due to an excessive fault current.
