The Circutor EC72 15A (code M10224) is a moving iron panel ammeter for quick visual monitoring of alternating current in electrical distribution and control panels. It covers a 15 A measurement range at class 1.5 accuracy and fits a standard 72 x 72 mm panel cutout, drawing no auxiliary power supply from the circuit under measurement.

Features and benefits:

• No auxiliary power supply required – the meter operates entirely from the measured current circuit, reducing wiring complexity
• Exchangeable scales are compatible across the EC48, EC72, EC96, EM 45, EC 72 FA and EC 96 FA series, so scale ranges can be swapped without replacing the instrument body
• True root mean square measurement technology across the EC series (100 mA to 100 A) delivers accurate readings regardless of waveform shape
• IP 52 rated front panel protects against dust and light moisture ingress in typical switchboard environments
• High overload tolerance – withstands 40 times rated current for 1 second and 1.2 times rated current continuously, providing protection against transient current surges

Applications:

• Visual AC current monitoring in low-voltage distribution boards and main switchboards
• Industrial control cabinets and machine panels requiring at-a-glance current indication
• Building electrical installations where circuit load must be checked without additional instrumentation
• Panel-metering systems using standard 72 x 72 mm DIN-format cutouts
