ELR-IF-0300 Type A Earth Leakage Relay with Integral Toroid

  • Type A – Earth Leakage Relay with Integral Toroid
  • Fixed Trip level (300mA) and Time delay (100ms)
  • Separate Test and Reset buttons
  • 1 x SPDT Relay output
  • DIN Rail or surface mount

This product incorporates a 25mm∅ toroid and will and will detect residual sinusoidal alternating and pulsating direct currents. It is offered with a fixed trip level and instantaneous tripping. Typically, the product is used in conjunction with an external switching device (i.e. contactor, shunt trip).
An auxiliary supply is required to power the product.

    • Monitoring function: Earth leakage
    • Trip level: 300mA
    • Time delay: 100ms
    • Output: 1 x SPDT 5A @ 250V (AC1)
    • Dimensions(mm): W:74 x H:110 x D:37

Aux. supply voltage options*:
120VAC (Order Code: 99-1125)
240VAC (Order Code: 99-1103)

* To be specified when ordering

Typical applications include:

  • Compact machinery panels
  • Building services control panels
  • OEM equipment cabinets
  • Small cable feeder assemblies

Key benefits:

  • Helps detect earth leakage — Type A residual-current monitoring can operate the relay output when leakage exceeds the 300mA trip threshold.
  • Enables a control response — The relay output can be used with an appropriately specified contactor or shunt-trip device when a fault is detected.
  • Supports commissioning checks — Separate Test and Reset buttons allow local checking and restoration.
  • Saves panel space — An integral 25mm toroid removes the need to mount a separate external sensor.
