20A 3-Phase RCD Testing Adaptor

The Model RCD-3P-20A is a 5-pin, 20 Amp, 3-phase RCD adaptor designed for testing 3-phase RCDs using a standard single-phase RCD tester or appliance tester with RCD testing capabilities.

The RCD-3P unit features three inbuilt 500V ceramic fuses (one fuse per phase) to prevent misuse. It is suitable for 5-pin, 3-phase installations only.

The adaptor provides the following test capability* 

• Earth continuity - No
• Insulation resistance - No
• Extension lead current leakage - No
• Appliance current leakage - No
• Polarity - Yes (L123/N only) - No
• RCD Trip Time/Trip Current - Yes
  
• Loop/Line Impedance - No
• Phase rotation/wiring - (L1-L1, L2-L2,L3-L3) - No
  

*Only in conjunction with suitable test instruments that have the required test functionality (not included):
