The Circutor EC96 /5A (code M10230) is a 96 x 96 mm panel-mount moving iron ammeter intended for use with current transformer (CT) secondaries rated at 5 A. It measures alternating current in true RMS across a frequency range of 20 to 100 Hz and presents readings on a 90-degree analogue scale at accuracy class 1.5. The instrument draws its operating power directly from the current measurement circuit, so no auxiliary power supply is required.

Features and benefits:

• No auxiliary power supply required – the meter is powered entirely by the measurement current circuit, reducing panel wiring complexity
• Exchangeable scales are compatible with EC48, EC72, EC96, EM 45, EC 72 FA, and EC 96 FA series instruments, simplifying replacements and recalibration
• True RMS measurement delivers accurate current readings even when waveforms are non-sinusoidal
• High short-duration overload tolerance – up to 40 times rated current for 1 second – protects the instrument against fault current surges
• IP 52 rated front panel resists dust ingress and water splashes in typical panel-mount environments

Applications:

• AC current monitoring in industrial motor control centres and switchgear via CT secondary connection
• Current indication in low-voltage distribution boards and busbar chambers
• Visual load monitoring in building electrical installations and consumer units
• Generator and transformer output current display in power distribution applications
