Phase Sequence and Motor Rotation Tester
Don’tsecondguessthree-phasesystems
If you install or connect 3-phase motors and systems, you recognize the importance of verifying the correct motor rotation
and wiring phase sequence. Improper connections can cause motors to rotate in reverse direction, potentially damaging the
motor and the equipment it is powering.
The PRM-6 Phase Sequence and Motor Rotation Tester can test the motor rotation of 3-phase systems and verify 3-phase
receptacle wiring and phase sequencing with test leads.
An additional advanced feature is wireless motor rotation detection, which senses motor rotation direction without use of
test leads. This is particularly useful for fast-running motors when the motor rotation cannot be visually determined or when
the drive shaft is not visible.
Durably constructed with a rubber outer casing, the PRM-6 has a bright, backlight LCD display, CAT IV 600 V rating, and
conforms to EN 61010 and EN 61557 standards, making it an essential tool for motor rotation and phase sequence testing in
commercial and industrial environments on electrical systems up to 700 V.

• Indicates the phase rotation in
3-phase systems for both power
sources and motors.
• Identiesfaulty3-phasewiringwith
de-energized phases or incorrectly wired
receptacles.
• Indicates motor rotation in
disconnected motors using test leads
and by spinning the shaft by hand or
other means.
• Tests for rotation direction on a
running motor with the built-in non-
contact, wireless sensor – specically
important for fast running motors or
motors where the shaft is not visible.
