Circutor M102Y9 SEC72 50/5A Scale

The Circutor SEC72 50/5 A Scale (code M102Y9) is an exchangeable replacement dial for the Circutor EC72 moving iron panel ammeter in 72 x 72 mm format. Graduated for a 50/5 A current transformer ratio, it allows the EC72 ammeter to display primary current directly on the scale face. The plate measures 60 x 60 x 1 mm and has a mass of just 0.004 kg.

Technical specifications:

• Model: SEC72 50/5 A Scale
• Circutor code: M102Y9
• EAN: 8433059002596
• Measurement range: 50/5 A
• Full scale: 50/5 A
• Compatible instrument: EC72
• Panel format (modules): 72 x 72 mm
• Scale plate dimensions: 60 x 60 x 1 mm
• Weight: 0.004 kg

Features and benefits:

• Exchangeable design allows the scale to be replaced independently of the EC72 ammeter body, avoiding the need to swap the full instrument
• 50/5 A graduation suits a 50 A primary / 5 A secondary current transformer, giving a direct primary current readout on the dial
• 60 x 60 x 1 mm plate format is matched to the 72 x 72 mm EC72 panel ammeter, ensuring accurate fit
• Very low mass of 0.004 kg adds negligible weight to the panel instrument assembly
• Part of the SEC72 scale family covering 5/5 A through 5000/5 A, making it straightforward to stock replacement scales for multiple CT ratios

Applications:

• Replacing a worn or damaged scale on an installed EC72 72 x 72 mm panel ammeter
• Re-ranging an EC72 ammeter following a current transformer change to a 50/5 A ratio
• New panel builds specifying 72 x 72 mm moving iron ammeters for 50 A primary current measurement
• Industrial switchboards and control panels where EC72 ammeters are used for feeder or branch circuit monitoring
