Kyoritsu 5406A RCD Tester

Key Features:

1. Comprehensive RCD Testing – Tests various types of RCDs, including:
   • AC Type RCDs (residual current devices)
   • A Type RCDs (for devices with DC residual currents)
   • Type B RCDs (for devices with mixed AC and DC residual currents)
2. Test for Tripping Time – Measures how quickly the RCD trips when a fault occurs, ensuring that it responds within required time limits for safety.
3. Test for Trip Current – Verifies that the RCD trips at the correct leakage current level, ensuring the protection is set properly for safety.
4. Wide Range of Testing – Can test RCDs across a range of current ratings and sensitivity, suitable for residential, commercial, and industrial applications.
5. Easy-to-Read Display – Features a large, clear display that shows test results, including tripping time and leakage current, for quick interpretation.
6. Portable and Lightweight – Designed for ease of use in the field, making it suitable for professionals who need to test RCDs during inspections, installations, or maintenance.
7. Built-in Safety Features – Includes protections to prevent errors during testing and ensure safe operation.
