ELR-V3 Earth leakage relay

ModelELR-V3

Product overview

The VTEKE ELR-V3 is an earth leakage relay designed to monitor RMS earth leakage current and provide protection against earth leakage faults. Used together with a Core Balance Current Transformer (CBCT), it continuously monitors leakage current and operates the relay output when the configured leakage current threshold and delay conditions are reached.

Applications

  • Designed for earth leakage monitoring and protection in electrical installations. Suitable for:
  • Industrial electrical systems
  • Motor and pump protection
  • Machinery and equipment protection
  • Control and automation panels
  • Distribution panels
  • Building electrical installations

Key features

  • RMS earth leakage current monitoring
  • Multiple selectable leakage current thresholds
  • Adjustable trip delay time
  • LED leakage level indication
  • On-device Reset and Test functions
  • Remote reset function
  • CBCT open-circuit detection
  • CBCT short-circuit detection
  • DIN rail mounting
