Amprobe 4375950 Description

Professionals who install or maintain 3-phase motors or systems recognize how crucial it is to verify 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’s powering. The PRM-6 Phase Sequence and Motor Rotation Tester is easy-to-use and reliable to test the motor rotation of 3-phase systems with traditional test leads. In addition, it can verify 3-phase receptacle wiring and phase sequencing. Durably constructed with a rubber outer casing, the PRM-6 has a bright backlight LCD display, CAT IV 600-volt 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. VERIFIES MOTOR ROTATION OF DISCONNECTED MOTORS: Indicates motor rotation in disconnected motors using test leads and by spinning the shaft by hand or other means. WIRELESS MOTOR ROTATION DETECTION ON RUNNING MOTORS: 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. PHASE ROTATION IN 3-PHASE SYSTEMS: Indicates the phase rotation. 3-phase systems for both power sources and motors, as well as identifies faulty 3-phase wiring with de-energized phases or incorrectly wired receptacles.
