The Greenlee 5124 is a professional-grade Phase Sequence and Motor Rotation Meter built for electricians and industrial technicians who need fast, reliable verification of three-phase power sources and rotating equipment. It detects live phase sequence and orientation to confirm proper installation of motors, compressors, and generators — and its non-contact motor rotation feature identifies the rotational direction of running single- and three-phase motors without requiring test leads. Rated CAT III 600V and operating across a wide frequency range of 15Hz to 400Hz, the 5124 is equally at home on industrial plant floors, commercial construction sites, and utility installations. The kit ships complete with tri-coloured banana leads, alligator clips, a 9V battery, and a soft carrying case so you’re ready to work right out of the box.
