Microprocessor Based,Digital ELR 30mA-3A

Prok dv’s brand earth leakage relay MPEL series uses the state of the art microcontroller based protection device to detect low level leakage due to degradation of insulation of phase conductors or high impedance faults.
The main feature of MPEL is the continuous display of earth leakage currents of the power system. The unit is immune to external disturbance like harmonics and transients.

• Microcontroller based compact design.
• Continuous monitoring and display of set value and measured value of leakage current
• 8 character 2line LCD displays with back lit
• Test & Reset facility
• CBCT connection monitoring facility
• True Rms measurement of leakage current
• Trip Circuit Failure indication (Optional) Default:Disabled
• Serial RS 485 communication port with modbus protocol (optional)
• Fault recording with date and time stampings, max up to 10 Faults (optional)
• Tropicalised and rugged design
• External test, reset, fault & healthy indication suitable for mining Application
• High sensitive leakage current setting (5mA to 1.00A) (MODEL:MPELSPL)
