Datasheet - MX0531

COO (Country of Origin):: CN

MX531 2P+E electric socket tester, earth & 30 mA RCD tests

The MX531 is a 3-in-1 controller that can be connected to any TT electrical socket to check that the electrical installation is operating correctly. This tester measures the voltage and displays the connections of the line, NEUTRAL and earth conductors in a 2P+E socket. The MX531 tester automatically measures the RE earth resistance Value without tripping any RCDs. This tester also tests the presence and the trip of the 30 mA RCD.

Strengths

Totally autonomous (no battery)

Immediate display without adjustments and with pictogram confirmation allowing an easy interpretation of the measurements

Compact size for easy use in confined spaces

Rotating head to adapt to all socket configurations

State at delivery

The MX531 is delivered in a NEUTRAL cardboard box with a coloured band, equipped with a carrying bag and a user's manual in 4 languages on paper.
