RCD test instrument

Measuring instrument for testing the characteristics of RCCBs.

In particular, this involves the measurement of touch voltage, breaking time and breaking current for type A, AC, and S RCCBs, as well as type F mixed frequency RCDs as of recently.

  • Digital display, backlit color OLED display
  • LED for measurement point illumination
  • Patented test probe retainer
  • Compact and rugged – for service calls under harsh conditions and laboratory use

Testing of residual current devices (RCCBs)

  • Measurement of touch voltage without tripping the RCCB. Touch voltage is measured with reference to nominal residual current using ⅓ of the nominal residual current value.
  • Tripping test with nominal residual current, measurement of time to trip

Special tests for systems and RCDs

  • Testing of systems and RCDs with rising residual current including indication of tripping current
  • Testing of RCDs, IΔN = 10, 30, 100, 300 und 500 mA
  • Testing of RCCBs with ½ΔN, 1ΔN, 2ΔN, 5ΔN up to100 mA nominal current
  • Testing of RCDs with half-waves (pulsating direct current) for determining time to trip and tripping current

Testing of special RCDs

  • Selective , type AC, type A

Measurement of line voltage and fault loop impedance
