Earth Leakage Relays Description: Application: 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. Product Part number Sensitivity Operation Time RCR-V30 30mA-30A 0-10 Seconds Ordering Information Required Supply Voltage 24V AC or 115 / 230V AC or 400V AC or 12-125V DC or 10-60V DC Frequency 50/60Hz or 400Hz 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. Specifications Supply Voltage (Un): 24, 115/230, 400V AC (85-115%) 12-125V DC (85-110%) 10-60V DC(90-110%) Power Consumption 6VA Ambient Temperature -20ºC to +55ºC Relative Humidity +95% Housing UL94VO Flame Retardent Weight 200g Mounting 35mm Din Rail Terminal Conducter = 2.5mm² stranded = 4mm² solid Output 1 x SPNO relay 1 x SPDT relay Terminal Protection: IP20 Approvals: IEC 60755, 60947, 62020, 61543 N.B. 210MM toroids should not be used for sensitivity settings of less than 300mA
