The Circutor SEC72 200/5A Scale (code M102YF) is an exchangeable replacement scale plate for the EC72 series moving iron ammeters. Calibrated for use with a 200/5 A current transformer, it displays primary currents up to 200 A on a 5 A secondary input, and is dimensioned to fit the 72 x 72 mm panel instrument format. The scale plate measures 60 x 60 x 1 mm and weighs 0.008 kg.

Technical specifications:

• Model: SEC72 200/5A Scale
• Circutor code: M102YF
• EAN: 8433059002770
• Measurement range: 200/5 A
• Full scale: 200/5 A
• Compatible instrument: EC72 (moving iron ammeter)
• Panel format (modules): 72 x 72 mm
• Scale plate dimensions: 60 x 60 x 1 mm
• Weight: 0.008 kg

Features and benefits:

• Exchangeable design allows the scale plate to be swapped independently of the ammeter body, so existing EC72 instruments can be recalibrated without full unit replacement
• 200/5 A rating corresponds to the common current transformer ratio used in distribution panels and switchgear carrying primary currents up to 200 A
• Slim 1 mm depth and 60 x 60 mm face plate integrates directly into the EC72 instrument housing without any modification to the panel cut-out
• Belongs to the SEC72 scale series, which covers CT ratios from 5/5 A through to 5000/5 A, making it straightforward to source matched scales across a wide range of installation ratings

Applications:

• Replacement of worn or damaged scale faces in EC72 moving iron ammeters fitted in existing switchgear or distribution boards
• Reconfiguring EC72 ammeters to a 200/5 A range when a panel current transformer ratio is changed during a refurbishment
• New panel builds requiring 72 x 72 mm format ammeters calibrated for a 200 A primary current with a 5 A secondary
• Industrial motor control centres and commercial LV distribution boards where 200/5 A current transformers are in use
