Kyoritsu 5406A RCD Residual Current Tester is a professional measuring instrument designed to test the operating functionality of Residual Current Devices (RCD), also known as Earth Leakage Circuit Breakers (ELCB) or Residual Current Circuit Breakers (RCCB).
- Large Digital Display: Clearly displays the tripping time result of the RCD with a minimum resolution of 1 ms.
- Wiring Status LED Indicators: Includes 3 LEDs for quick and intuitive checking of wire connection status (phase, neutral, earth), including detection of reversed phase and neutral wires.
- Multi-RCD Testing Function: Capable of testing common RCD types such as:
- Standard: Conventional RCD.
- Selective: RCD with time delay to ensure selectivity in multi-tier electrical systems.
- AC Type: RCD sensitive to alternating current leakage.
- A Type (DC sensitive breakers): RCD sensitive to AC and pulsating DC leakage currents.
- Fault Condition Settings:
- ×1/2: Test RCD for over-sensitivity (tripping at half the nominal value).
- ×1: Test RCD at rated current.
- ×5: Test RCD at 5 times rated current (to evaluate tripping speed).
- ×DC: Test Type A RCD with pulsating DC leakage current.
