The Circutor SEC72 2000/5A (code M102YS) is an exchangeable replacement scale for the EC72 series moving iron ammeter. It covers a measurement range of 2000/5 A, meaning the instrument will display primary currents up to 2000 A when fed from a current transformer with a 5 A secondary. The scale plate itself measures 60 x 60 x 1 mm and fits the 72 x 72 mm panel-format EC72 instrument.

Technical specifications:

• Model: SEC72 2000/5A
• Circutor code: M102YS
• EAN: 8433059003067
• Measurement range: 2000/5 A
• Full scale: 2000/5 A
• Compatible device: EC72 moving iron ammeter
• Panel instrument format: 72 x 72 mm
• Scale plate dimensions: 60 x 60 x 1 mm
• Weight: 0.004 kg

Features and benefits:

• Exchangeable construction allows the EC72 ammeter measurement range to be changed without replacing the entire instrument
• 2000/5 A ratio pairs directly with standard 2000/5 A current transformer secondaries, removing the need for recalculation or rescaling
• At only 1 mm thick, the scale plate seats flush within the EC72 dial housing without any modification to the instrument
• Extremely low weight of 0.004 kg makes field installation straightforward and quick
• Part of the SEC72 exchangeable scale family spanning 5/5 A to 5000/5 A, so a different range can be installed at a later date by fitting the appropriate scale only

Applications:

• Replacing a worn or illegible scale face on an EC72 panel ammeter in a low-voltage distribution board
• Reconfiguring an existing EC72 ammeter after a current transformer upgrade to a 2000/5 A ratio
• New panel builds requiring 72 x 72 mm format CT-connected ammeter indication for primary currents up to 2000 A
• Current monitoring in industrial switchgear, motor control centers, and substation LV boards where high primary currents are measured via instrument transformers
