for checking the 3 phase 400V/50Hz power requirement with neutral conductor.
Power supply monitoring with disconnection if faults occur. Robust IP65 metal casing construction, approx. 150x150x120mm with a control lamp.
Indicator light lights up: Neutral conductor, phase L1, L2, L3 available, rotating field clockwise.
Indicator lamp off:
- Rotating field anticlockwise and/or
- Neutral conductor missing, or not potential free and/or
- Phase L1 and/or L2 and/or L3 are missing.
Phase sequence can be changed at the plug.
Connection with a length of cable with CEE-male coupling and a length of cable with a CEE female coupling, both approx. 0.5m.
