The Circutor SEC72 800/5 A (code M102YN) is an exchangeable scale for Circutor EC72 moving iron ammeters. This printed dial face is calibrated to an 800/5 A current transformer ratio and fits panel instruments in the 72 x 72 mm module format. The scale itself measures 60 x 60 x 1 mm and weighs 0.004 kg.

Technical specifications:

• Model: SEC72 800/5 A
• Circutor code: M102YN
• EAN: 8433059002961
• Measurement range: 800/5 A
• Full scale: 800/5 A
• Compatible device: EC72 moving iron ammeter
• Panel module format: 72 x 72 mm
• Scale dimensions: 60 x 60 x 1 mm
• Weight: 0.004 kg

Features and benefits:

• Exchangeable design allows the dial face to be swapped without removing or replacing the entire EC72 ammeter instrument from the panel
• Calibrated to an 800/5 A current transformer ratio, enabling clear primary-side current readings from a 5 A secondary CT output
• Matched to the EC72 platform in the 72 x 72 mm format, ensuring a correct mechanical fit when installed
• Compact and lightweight at 60 x 60 x 1 mm and 0.004 kg, making handling and installation straightforward during maintenance
• Part of the SEC72 scale series covering ratios from 5/5 A to 5000/5 A, allowing flexible CT ratio matching across different panel configurations

Applications:

• Replacing a worn or damaged dial face on a Circutor EC72 moving iron ammeter fitted in a switchboard or distribution panel
• Reconfiguring an existing EC72 ammeter to indicate an 800/5 A range after a current transformer or primary circuit has been upgraded
• Maintenance stock for facilities managing multiple panels fitted with EC72 ammeters at varying CT ratios
• Industrial and commercial electrical installations where 800 A primary current circuits are monitored via 5 A secondary CT outputs requiring analogue indication
