Fluke 9040 Phase Rotation Tester 15 Hz, 400 Hz Max, 700V Max

Fluke Phase Rotation Tester, 700V Maximum Voltage, 400Hz Maximum Frequency - FLUKE 9040/UK

This phase rotation tester is a portable instrument for determining phase sequence and rotation direction on three-phase supplies used with motors, drives and electrical systems. It operates from the circuit under test and displays the three-phase indication on a clear LCD, enabling quick verification of correct connections in commercial and industrial settings.

Features & Benefits

• Voltage measurement range 40V–700V for higher-voltage systems
  Frequency capability 15–400Hz to cover varied supply types
  Mains powered operation requiring no batteries for continuous use
  Low current draw of 1mA to minimise circuit loading during tests
  Lightweight 200g construction for easy transport and handling
  Protective probe clamping for secure contact in industrial sockets

**Applications**

• Suitable for commissioning three-phase motors and drives
  Ideal for verifying rotation before coupling pumps and compressors
  Used with control panels to confirm correct phase sequence
  Can be used for troubleshooting supply issues in factories
  Used for field checks on variable-frequency drive installations

How is the device powered during measurement?

It draws its operating power directly from the unit under test so no separate battery is required.

What environmental conditions can it withstand during use?

It is rated to function in ambient temperatures between 0°C and 40°C and offers Basic dust protection consistent with light industrial environments.

What safety categories and standards are applicable?

The instrument meets EN 61010 and EN 61557-7 standards and is specified for overvoltage categories CAT III up to 600V and CAT IV up to 300V.

What accessories are supplied for connection to the supply?

The kit includes three self-retaining test probes and an alligator clip to facilitate secure contact with conductors and sockets.
