Gossen Metrawatt M507B - RCD Test Instrument
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 an indication of tripping current
- Testing of RCDs, I?N = 10, 30, 100, 300 and 500 mA
- Testing of RCDs with half-waves (pulsating direct current) for determining the time to trip and tripping current
Testing of special RCDs
- Selective, type AC, type A
