The Circutor EC72 F III+N 600V (code M10729) is a panel-mounted analogue voltmeter with an integrated phase switch for AC voltage measurement in three-phase 4-wire systems. It covers a measurement range up to 600 V with a class 1.5 accuracy and mounts in a standard 72 72 mm panel cutout. The 90 scale with P1 deflection provides a clear, direct voltage reading for each phase and neutral selection.

Features and benefits:

• The built-in phase switch allows a single instrument to display each phase-to-neutral voltage in a three-phase 4-wire system, cutting the number of meters required on the panel.
• IP 52 front protection guards the movement and dial against dust ingress and dripping water, making it suitable for typical industrial enclosure front panels.
• A frequency tolerance of 20 – 100 Hz covers both standard 50 Hz and 60 Hz grid supplies, broadening the range of installations where this meter can be used.
• The compact 72 72 mm form factor fits standard DIN-compliant panel cutouts for straightforward new installation or retrofit.
• Class 1.5 accuracy with compliance to BS 89, IEC 51, and UNE-EN 60051 satisfies the measurement requirements for industrial switchgear and control panels.

Applications:

• Phase-to-neutral voltage monitoring in three-phase 4-wire low-voltage distribution boards and switchgear assemblies.
• Industrial control cabinet instrumentation requiring local analogue voltage display up to 600 V.
• Building services and commercial electrical installations with three-phase 4-wire LV networks.
• Generator and UPS output panels needing on-panel analogue voltage indication across all phases.
