Checking for live stock

The Fluke 377 FC/E is a professional-grade AC/DC clamp meter developed for technicians demanding fast, accurate electrical measurements in industrial and commercial power systems. The meter supports measurements up to 2.5 kA ac and is safety-rated CAT III 1000 V and CAT IV 600 V, making it suitable for high-energy circuits, switchgear, feeders, and distribution panels.

Crucial Features and Benefits of the Fluke AC/DC Clamp Meter CAT III 1000 V, CAT IV 600 V

  • FieldSense technology enables voltage and current measurement without contacting live conductors.
  • Measures up to 2.5 kA ac for heavy-duty industrial load assessments.
  • CAT III 1000 V and CAT IV 600 V ratings for work on large distribution systems.
  • True-RMD capability ensures accurate readings on variable-speed drives and non-linear loads.
  • Wireless connectivity via Fluke Connect for data logging, trend capture and team sharing.
  • Large jaw opening and slim profile allow access around tight, crowded conductors.

Built Tough for Industrial-grade Testing

The 377 FC/E is built to provide technicians with dependable, repeatable measurement performance in environments where equipment density, high currents and safety demands are routine. Its FieldSense sensing architecture reduces probe handling and allows safer testing around energised busbars and feeders. The instrument’s rugged housing, clear display and intuitive control layout support everyday plant maintenance, commissioning and troubleshooting tasks. Its ability to capture current, voltage, frequency and phase relationships makes the meter a reliable tool for diagnosing load issues and verifying system operation.

Applicable Areas of the Meter

  • Testing high-current industrial feeders, MCC outputs and distribution circuits.
  • Troubleshooting motors, drives and heavy mechanical loads with true-RMS assessment.
  • Verifying voltage and current behaviour in control panels without exposing bare conductors.
  • Commissioning electrical installations in manufacturing, utilities and commercial facilities.
  • Field diagnostics where remote logging and team data sharing improve maintenance workflow.
