Circutor M10222 EC72 5A Ammeter

The Circutor EC72 5A (code M10222) is a moving iron panel ammeter for alternating current measurement. It measures AC current up to 5 A with class 1.5 accuracy and mounts into a standard 72 x 72 mm panel cutout, providing direct visual current readout in electrical distribution boards and control panels without requiring a separate auxiliary power supply.

Features and benefits:

• No auxiliary power supply needed: the instrument draws its operating power from the measurement circuit itself (0.3 to 1.5 VA), simplifying wiring and reducing installation complexity.
• True RMS measurement across a frequency range of 20 to 100 Hz ensures accurate current readings regardless of waveform variations in AC circuits.
• IP 52 front-face protection guards against dust and water splash in panel environments, making the meter suitable for industrial and commercial switchboard installations.
• Exchangeable scales are compatible with EC48, EC72, EC96, EM 45, EC 72 FA, and EC 96 FA series instruments, allowing dial replacement without removing the instrument body.
• Overload tolerance up to 40 times rated current for 1 second protects the meter against momentary fault currents in AC distribution systems.

Applications:

• Visual AC current monitoring in industrial and commercial electrical distribution boards.
• Motor control centers and switchgear panels requiring a compact 72 x 72 mm analogue current indicator.
• Building electrical installations where quick visual confirmation of current flow is needed without auxiliary power wiring.
• Control panel instrumentation in AC systems operating between 20 and 100 Hz.
