Voltmeter (moving iron) with switch
Dimensions - see table below
A range of moving iron AC Voltmeters with integral selection switch in 72 or 96mm square DIN format for use
on AC supplies. Two versions are available namely: FNlll for phase to phase selection and FNlll+N for phase
to phase and phase to neutral voltage selection.
Application
The EC72/96 FN Voltmeter with integral manual
changeover switch is specifically designed to
measure the voltages between phases and between
each phase and neutral of a three phase AC
system.
The switch on the FNlll has three positions :-
L1 phase to L2 phase
L2 phase to L3 phase
L3 phase to L1 phase
On the FNlll+N it has six positions :-
L1 phase to L2 phase
L2 phase to L3 phase
L3 phase to L1 phase
L1 phase to Neutral
L2 phase to Neutral
L3 phase to Neutral
Each phase connection to the Voltmeter should be
protected by a fuse.
The scale has a 90 degree movement with zeroing
adjustment.
