The Circutor SEC72 FA 600/5A (code M105YL) is an exchangeable scale face for the EC72 FA moving iron ammeter. It provides a full-scale reading of 600/5 A, making it suited to current transformer-based panel measurement of high AC currents. The scale is designed for 72 72 mm panel-mount instruments and can be swapped to reconfigure the displayed range without replacing the complete meter body.

Technical specifications:

• Model: SEC72 FA 600/5A
• Circutor code: M105YL
• EAN: 8433059004927
• Full scale: 600/5 A
• Compatible device: EC72 FA
• Panel module: 72 72 mm
• Scale dimensions: 60 60 1 mm
• Weight: 0.004 kg

Features and benefits:

• Exchangeable design allows the displayed current ratio on an EC72 FA ammeter to be updated without sourcing a new instrument
• 600/5 A full scale covers a wide range of CT-fed distribution and industrial circuits where primary currents reach 600 A
• Sized to fit 72 72 mm panel-mount ammeters precisely, ensuring correct scale alignment and clear readability
• Ultra-thin 1 mm profile and minimal weight of 0.004 kg simplify fitting and impose no mechanical stress on the instrument
• Part of an extensive SEC72 FA family spanning 50/5 A to 5000/5 A, providing a consistent replacement option across a wide range of site CT ratios

Applications:

• Reconfiguring an existing EC72 FA ammeter following a CT ratio change in a low-voltage distribution board
• Replacing a worn or damaged scale face on a 72 72 mm moving iron panel ammeter
• Industrial control panels and motor control centres requiring 600 A current monitoring via a 600/5 A current transformer
• Maintenance inventory for sites that standardise on Circutor EC72 FA panel instrumentation
