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 Dimensions 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.
