April 15, 2019

Emerson introduces the new Greenlee Phase Sequence and Motor Rotation Indicator (5124). Backed by a manufacturer’s lifetime limited warranty, electrical contractors, HVAC/IR and industrial maintenance technicians can use one device to identify motor rotation direction and clockwise or counterclockwise wiring configuration in a three-phase power source—safeguarding to ensure proper installation. The Phase Sequence and Motor Rotation Indicator is now available.

The new Phase Sequence and Motor Rotation Indicator is rated CAT III 600V and is CE, CETLUS certified. The phase sequence indicators illuminate when three phase power is detected and phase sequence orientation for three-phase power sources and industrial equipment is identified.  A non-contact motor rotation feature determines the rotation of a running single-phase or three-phase motor and illuminates clockwise or counterclockwise motor rotation LED indicators to detect incorrect wiring and help prevent damage to industrial equipment. The new Phase Sequence and Motor Rotation Indicator features tri-colored banana leads, alligator clips, soft carrying case and a durable over molded holster protecting the meter from debris and damage.

“Motor rotation detection is critical when working on industrial equipment such as motors, compressors and generators,” said Katey Earley, Product Specialist for Greenlee, Emerson. “If not done properly, maintenance or repairs could result in expensive, complicated or permanent damage.”
