The Circutor SEC72 125/5A Scale (code M102YD) is an exchangeable replacement scale for Circutor EC72 moving iron ammeters. It displays a measurement range of 125/5 A, making it suited for use with current transformers that have a 5 A secondary output and a primary current up to 125 A. The scale is sized for the 72 x 72 mm EC72 panel-mount ammeter and measures 60 x 60 x 1 mm.

Technical specifications:

• Model: SEC72 125/5A Scale
• Circutor code: M102YD
• EAN: 8433059002725
• Measurement range: 125/5 A
• Full scale: 125/5 A
• Compatible device: EC72
• Panel module format: 72 x 72 mm
• Scale dimensions: 60 x 60 x 1 mm
• Weight: 0.008 kg

Features and benefits:

• Exchangeable design allows the scale face to be replaced or swapped on an EC72 ammeter without replacing the entire instrument
• 125/5 A range matches standard current transformers with a 5 A secondary, covering primary currents up to 125 A
• Sized specifically for the EC72 72 x 72 mm ammeter body, ensuring correct fit and accurate dial alignment
• Slim 1 mm profile and low weight of 0.008 kg simplify handling, storage, and installation
• Part of a broad SEC72 scale family covering many CT ratios, allowing the same EC72 meter body to be reconfigured for different measurement ranges

Applications:

• Replacing a worn or damaged scale on an installed Circutor EC72 72 x 72 mm moving iron ammeter
• Reconfiguring an EC72 ammeter to read a 125/5 A range after a current transformer change or panel redesign
• New panel builds where EC72 ammeter bodies and scales are sourced separately to match site CT ratios
• Low-voltage distribution boards, industrial switchgear, and motor control centres requiring panel-mounted current indication
