Features and benefits:

• Draws power directly from the measured AC circuit, so no separate auxiliary supply is needed.
• True RMS measurement across a 20 to 100 Hz range gives accurate readings regardless of waveform shape.
• Scale dials are interchangeable across the EC48, EC72, EC96, EM 45, EC 72 FA, and EC 96 FA meter families, simplifying spares management.
• IP 52 front protection guards against dust ingress and water drips in panel and switchgear enclosures.
• Rated overload tolerance of 40 In for 1 second protects the instrument during short-circuit fault events.

Applications:

• Current monitoring in industrial motor control centres and low-voltage distribution panels.
• Feeder and branch circuit current indication in switchgear assemblies.
• Current supervision in building services and facility electrical installations.
• Drop-in replacement for existing panel ammeters with a 72 × 72 mm cutout.
