Metrel A 1111 3-Phase Adaptor 32A Metrel MI-TPI 32

This 3-phase socket testing adaptor makes verifying 3-phase installations safer and more efficient—without the need for probing. Designed for use with the Metrel InstalTest 3XC (3152), XD (3155), 3122, 3155 or 3017, the MI-TPI connects directly to the mains socket, allowing you to switch between phases with ease.

Simply select the test function on your tester, choose the corresponding switch position on the MI-TPI, and use the selector to move through phase combinations—no exposed terminals or manual probing required.

Switch positions include:

• Insulation Testing: Phase to Neutral, Between Phases, Phase/Neutral to Earth
• Loop/Line Impedance: L1–N/PE, L2–N/PE, L3–N/PE
• RCD Testing: L1–N/PE, L2–N/PE, L3–N/PE
• Phase Sequence & Voltage Checks
• Compatible with both standard and custom 3-phase plug configurations, the MI-TPI offers a reliable and user-friendly solution for 3-phase socket verification.

• 32A 3-Phase Plug (5 Pin) - 4 pin available on request
