2D Series

Features:



ELR /EFR (Static/Digital) -2D Series

A Wide Range of 2D Earth Leakage Relay (ELR)  with Core Balance Current Transformer (CBCT) are used to detect leakage / Fault currents in electrical power systems.

Applications:  Earth leakage Protection & Earth Fault Protection.

Brands:Prok Dvs

Description

Earth leakage Current give rise to generation of heat and result in progressive failure of insulation ,which leads to earth faults ,sparking flashovers, deterioration of earthling and finally results in catastrophic which destroys costly equipment’s, gadgets and precious lives. It is therefore essential to detect earth leakage current well before they cross the threshold limits and isolate circuit in the event of leakage.

KEY FEATURES
  • Consistent reliability with accuracy
  • Static Design / Digital Design
  • Sensitivity : 30mA to 30A / 5% – 80%
  • Mounting – DIN
  • LED indication of fault
  • High barrier connector at rear end for easy termination and safety standard
  • Test & Reset facility for testing healthiness of the relay
  • Tamper proof polycarbonate cover in the front
