The Circutor SEC72 75/5 A (code M102YB) is an exchangeable scale for Circutor EC72 moving iron ammeters fitted in 72 72 mm panel cutouts. It covers a 75/5 A measurement range, displaying primary currents up to 75 A when the ammeter is fed from a 5 A secondary current transformer. This slim replacement scale allows the instrument face to be updated or restored without removing or replacing the ammeter body.

Technical specifications:

• Model: SEC72 75/5 A
• Circutor code: M102YB
• EAN: 8433059002664
• Measurement range: 75/5 A
• Full scale: 75/5 A
• Compatible instrument: EC72 moving iron ammeter
• Panel module format: 72 72 mm
• Scale dimensions: 60 60 1 mm
• Weight: 0.004 kg

Features and benefits:

• Exchangeable design lets maintenance staff swap the scale face without dismantling the ammeter, cutting panel downtime
• 75/5 A range works directly with standard 5 A secondary current transformers used on circuits up to 75 A
• Thin 1 mm profile and precise 60 60 mm footprint seats flush inside the EC72 72 72 mm instrument housing
• At 4 g, the scale is easy to handle and carry as a spare part on site
• Part of the SEC72 series spanning 5/5 A to 5000/5 A, enabling the same EC72 ammeter body to be reconfigured for different circuits

Applications:

• Replacing worn, faded, or damaged dials on Circutor EC72 moving iron ammeters in low-voltage switchboards
• Reconfiguring an existing EC72 panel ammeter to a 75/5 A range when distribution circuit ratings change
• Stocking spares for facilities that operate multiple Circutor EC72 ammeters across industrial or commercial installations
• Panel refurbishment projects where current-transformer-fed instrumentation must be re-ranged without full meter replacement
