## Summary description

The Sonel MRP-201 (WMPLMRP201) is a residual current protection tester designed to check RCDs and residual current devices. It verifies operation of protective devices by applying test currents and observing tripping behavior, helping electricians and service technicians confirm safety and compliance. Portable and purpose-built for on-site inspections and maintenance.

## Long description

The Sonel MRP-201 (WMPLMRP201) is a portable residual current protection tester designed for on-site verification of all types of residual-current devices (RCDs) including type AC, A and B, as well as no-delay, short-delay and selective RCDs. It measures trip current and trip time as a function of differential current, protective conductor resistance and touch voltage. Measurements can be performed individually or in automatic series modes, and the instrument can record simultaneous current and time during a single RCD actuation. The tester stores measurement results and communicates with a PC via a radio interface for protocol generation and data analysis.
Advantages
The device supports measurements for rated residual currents of 10, 30, 100, 300 and 500 mA and provides measurement of trip current (IA), trip time (tA) at multiple multiples of IΔn (0.5, 1, 2, 5) and simultaneous IA/tA capture. It also measures protective conductor resistance (RE), touch voltage (UB) without tripping the RCD, AC voltage and frequency, and checks protective conductor connections. Results memory stores up to 990 cells and 10,000 entries, and included radio interface and professional PC software enable remote data transfer and report creation. The tester meets double insulation requirements and relevant safety categories for electrical test equipment and provides an IP67 enclosure rating.
Suitable for
Verification and commissioning of RCDs and residual current devices on-site
Periodic inspections and maintenance by electricians and service technicians
Measuring trip current, trip time, protective conductor resistance and touch voltage
Documentation and reporting of test results using PC software
Key specifications
Supported RCD types: AC, A, B; no-delay, short-delay and selective
Rated residual currents: 10 mA, 30 mA, 100 mA, 300 mA, 500 mA
Trip time measurement ranges (depend on type and multiple of IΔn): up to several hundred milliseconds per IEC 61557
Trip current measurement ranges per IEC 61557 for sinusoidal, pulsating and DC differential currents (examples: 3.3–10.0 mA for 10 mA nominal; up to 150–500 mA for 500 mA nominal)
Touch voltage (UB) range: 10.0–99.9 V (resolution 0.1 V)
Protective conductor resistance (RE) measurement ranges dependent on nominal test current (examples: 0.01–5.00 kΩ for 10 mA test current; 1–100 Ω for 500 mA test current)
AC voltage measurement: 0.0–299.9 V (0.1 V resolution) and 300–500 V (1 V resolution); frequency 45–65 Hz
Memory: 990 cells, up to 10,000 entries
Data transfer: radio interface (included) and PC software for reading and protocol generation
Safety and environmental: double insulation, measurement category CAT IV 300 V (CAT III 600 V), enclosure protection IP67
Power supply: rechargeable battery pack or 4 × AA alkaline batteries
Operating conditions: temperature -10…+50 °C, storage -20…+70 °C, humidity 20…80%
How to use
Connect the tester to the installation according to the user manual: attach leads to the circuit under test and to the protective conductor where required. Select the appropriate RCD test function and set the desired multiple of IΔn or use the AUTO mode to run a predefined sequence of tests. Start the measurement; the instrument will apply the test current and record trip current, trip time and additional parameters. Use the simultaneous IA/tA function if both current and time must be captured during one actuation. After testing, transfer stored data to a PC using the supplied radio interface and the professional software to generate protocols and archive results.
Usage recommendations
Perform measurements in accordance with national standards and safety procedures. Ensure the installation is isolated or the test is carried out under safe conditions, use appropriate personal protective equipment and verify connections before applying test currents. Calibrate and service the instrument as recommended by the manufacturer.
