The Amprobe PRM-6 Phase Sequence and Motor Rotation Tester is designed to test the motor rotation of 3-phase systems and verify 3-phase receptacle wiring and phase sequencing with test leads. Anyone who installs or services 3-phase motors and systems 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 Amprobe PRM-6 Phase Sequence and Motor Rotation Tester not only indicates the phase rotation in 3-phase systems for both power sources and motors, but is also capable of identifying faulty 3-phase wiring with de-energized phases or incorrectly wired receptacles. The PRM-6 can also indicate motor rotation in disconnected motors using test leads and by spinning the shaft by hand or other means as well as test for rotation direction on a running motor with the built-in non-contact, wireless sensor – specifically important for fast running motors or motors where the shaft is not visible. . 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 Amprobe 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.
