The Circutor SEC72 100/5A (code M102YC) is an exchangeable dial scale for Circutor EC72 moving iron ammeters in a 72 x 72 mm panel format. Calibrated for a 100/5 A current transformer ratio, it lets the ammeter face display primary current up to 100 A when paired with a matching 100 A / 5 A CT. The slim 60 x 60 x 1 mm scale slots in place of the existing dial, updating the displayed measurement range without removing or replacing the full instrument.

Technical specifications:

• Model: SEC72 100/5A
• Circutor code: M102YC
• EAN: 8433059002695
• Measurement range: 100/5 A
• Full scale: 100/5 A
• Compatible instrument: EC72
• Panel format (modules): 72 x 72 mm
• Scale dimensions: 60 x 60 x 1 mm
• Weight: 0.004 kg

Features and benefits:

• Exchangeable construction allows the ammeter range to be updated in the field without removing or replacing the base instrument
• Calibrated for a 100/5 A CT ratio, covering installations with a 100 A primary current and a 5 A secondary output
• Dimensioned precisely for the EC72 instrument body within a 72 x 72 mm panel cutout
• Ultra-slim 1 mm thickness and 0.004 kg weight make fitting straightforward with no added burden to the panel assembly

Applications:

• Replacing worn or illegible dial faces on EC72 moving iron ammeters already in service
• Reconfiguring an existing 72 x 72 mm panel ammeter to match a newly installed 100/5 A current transformer
• New switchboard or distribution panel builds requiring a 72 x 72 mm ammeter scaled for 100/5 A CT measurement
• Maintenance and refurbishment of industrial motor control centres and low-voltage switchgear panels
