Circutor M105YE SEC72 FA 150/5A Scale

Circutor SEC72 FA 150/5 A (code M105YE) is an exchangeable scale face for the EC72 FA moving iron panel ammeter. The scale carries a 150/5 A full-scale marking, compatible with a 5 A secondary current transformer input measuring up to 150 A on the primary side, and fits the 72 x 72 mm instrument module format.

Technical specifications:

• Model: SEC72 FA 150/5 A
• Circutor code: M105YE
• EAN: 8433059004828
• Full scale: 150/5 A
• Compatible device: EC72 FA moving iron ammeter
• Panel module size: 72 x 72 mm
• Scale dimensions: 60 x 60 x 1 mm
• Weight: 0.004 kg

Features and benefits:

• Exchangeable design allows the scale face to be swapped without replacing the complete ammeter, reducing maintenance time and cost.
• 150/5 A full-scale range suits current transformer secondaries of 5 A, enabling measurement of primary currents up to 150 A.
• Compact 60 x 60 x 1 mm plate fits precisely into the EC72 FA 72 x 72 mm panel cutout, giving a flush and accurate installation.
• Very low weight of 0.004 kg has no effect on the balance or operation of the moving iron mechanism.
• Part of a broad SEC72 FA range spanning 50/5 A to 5000/5 A, making it straightforward to match or update the displayed scale as measurement requirements change.

Applications:

• Replacing worn, damaged, or illegible scale faces on EC72 FA moving iron ammeters in existing switchboard panels.
• Reconfiguring panel instruments after a current transformer ratio change, where the displayed full scale must reflect the new primary current.
• New-build electrical panels requiring 72 x 72 mm format moving iron ammeters connected to a 5 A CT secondary.
• Panel refurbishment projects where EC72 FA instruments are being re-used and need fresh, clearly readable scale faces.
