The Circutor SEC72 250/5A (code M102YG) is an exchangeable scale for EC72 series moving iron ammeters. It replaces or re-ranges the dial face of an EC72 panel ammeter to display primary current measured via a current transformer at a 250/5 A ratio. The scale is sized for the 72 x 72 mm module format and measures 60 x 60 x 1 mm.

Technical specifications:

• Model: SEC72 250/5A
• Circutor code: M102YG
• EAN: 8433059002794

• Full scale: 250/5 A
• Compatible device: EC72
• Module format: 72 x 72 mm
• Scale dimensions: 60 x 60 x 1 mm
• Weight: 0.009 kg

Features and benefits:

• Exchangeable design lets you replace or re-range the scale without removing the ammeter body from the panel
• 250/5 A ratio matches current transformers delivering a 5 A secondary signal from primary currents up to 250 A
• Slim 1 mm thickness fits flush within the EC72 ammeter housing without modification
• 60 x 60 mm face is purpose-made for the 72 x 72 mm panel cut-out used by EC72 instruments
• Weighs only 0.009 kg, making handling and on-site fitting straightforward

Applications:

• Replacing worn or damaged dial scales on EC72 moving iron ammeters in industrial switchgear panels
• Re-ranging an existing EC72 ammeter to suit a 250/5 A current transformer installation
• Distribution boards and motor control centres fitted with 72 x 72 mm format panel instruments
• Maintenance and refurbishment of EC72 ammeters where only the scale requires renewal
