Amprobe PRM-6 - Phase Sequence and Motor Rotation Tester

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 Motor and Phase 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.

Identifies faulty 3-phase wiring with 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 – specifically important for fast running motors or motors where the shaft is not visible.
