WM12 DIN and WM12 96 are general purpose multi
function meters that allow to monitor all the mains
parameters of an electrical line or load. The compact
housings combined with a complete selection of
measurements allow the instruments to be mounted in all
the switch and control gears as local indicators, instead of
the classical single function analogue or digital panel
meters.
The unit is provided with some unique installation visual
status functions like:
• The window control of the mains 3-phase voltage
notifying the user, at a glance, if the mains is supplied
out of the requested power supply tolerance.
• The neutral current control showing immediately any load
or installation anomaly, due to high harmonic distortion
or load insulation loss (high earth leakage current).
