Contact us at sales@hoytmeter.com for availability and price

ELRM44V-30 Earth Leakage Relay is used in conjunction with an external Core Balance Current Transformer (CBCT) and will detect residual sinusoidal alternating and pulsating direct currents.

  • 44mm (2.5 modules) wide DIN rail housing
  • Designed to monitor and detect true RMS earth fault currents (up to 30A) in conjunction with a separate toroid
  • LED bar graph provides constant indication of any leakage current
  • Microprocessor controlled with internal monitoring (self-checking)
  • Adjustable Sensitivity (I∆n) - 30mA to 30A
  • Adjustable Time Delay (∆t) - 0 (instantaneous)* to 10 seconds
  • Separate “Test” and “Reset” push buttons
  • Connection facility for remote “Test” and “Reset” push buttons or N.O. contacts
  • Toroid open circuit detection forces unit to trip (Red LED flashes during this condition)
  • 2 Relay outputs - Standard Output (S.O.) and Positive Safety Output (P.S.O.)
  • LED indication of supply status and fault condition after unit has tripped
