Circutor SEC72 2500/5A Scale (code M102YT) is an exchangeable replacement scale for the EC72 moving iron ammeter. It is calibrated for a 2500/5 A current transformer ratio, enabling the panel instrument to display primary currents up to 2500 A when fed from a 5 A CT secondary. The scale is sized for EC72 instruments mounted in 72 x 72 mm panel cutouts.

Technical specifications:

• Model: SEC72 2500/5A Scale
• Circutor code: M102YT
• EAN: 8433059003081
• Measurement range: 2500/5 A
• Full scale: 2500/5 A
• Compatible instrument: EC72 moving iron ammeter
• Panel format (modules): 72 x 72 mm
• Scale face dimensions: 60 x 60 x 1 mm
• Weight: 0.004 kg

Features and benefits:

• Exchangeable design means the scale can be swapped out without replacing the entire EC72 ammeter, reducing maintenance cost
• Calibrated for the 2500/5 A CT ratio, making it suitable for measuring high primary currents in industrial installations
• Thin 1 mm profile and compact 60 x 60 mm face allow straightforward fitting into existing EC72 panel instruments
• At just 4 g, the scale adds negligible weight and does not affect instrument balance or pointer movement

Applications:

• Replacement of worn, damaged, or illegible scales in installed EC72 panel ammeters
• Re-ranging an EC72 ammeter to match a 2500/5 A current transformer in an upgraded installation
• Maintenance and refurbishment of panel switchboards and MV/LV distribution boards
• Industrial control panels where currents up to 2500 A are monitored via 5 A secondary CTs
