The PEAKMETER MS5909 is a professional RCD and leakage-switch tester for single-phase and three-phase installations. Multiple test-current multipliers, automatic ramp testing and selectable 0°/180° phase angles allow electricians and commissioning teams to verify trip current, trip time, wiring condition and protective-device operation.
Key features
- ½×, 1×, 2× and 5× rated residual-current tests
- Automatic ramp test from 40% to 110% of selected current
- 0° and 180° phase-angle selection
- Test currents from 10 mA to 500 mA, depending on mode
- Single-phase 2/3-wire and three-phase 3/4-wire support
- Wiring, fault-voltage and over-temperature protection
- 99-result memory
Applications
- RCD and earth-leakage device commissioning
- Electrical certificate-of-compliance support testing
- Industrial distribution-board inspection
- Commercial and residential installation maintenance
- Trip-time and ramp-current fault investigation

Calibration
Optional CNAS calibration is available through Peakmeter's qualified external calibration partner. A CNAS calibration report is already available for the MS5909 model. If a certificate for the specific supplied serial-numbered unit is required, calibration must be ordered before dispatch and is quoted separately.
