Description
Variable Earth Leakage Relays in compact 35mm din rail mounting cases for use on 3 phase electrical systems.
Application
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.
