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

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.

• 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

• 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

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

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

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.

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