The Greenlee 5124 Phase Sequence and Motor Rotation Meter is a professional-grade diagnostic tool for verifying live phase sequence and motor rotation direction in three-phase powe r systems and industrial equipment. With a CAT III 600V rating, CE and CETLUS compliance, and a non-contact motor rotation feature, the 5124 is built for electricians and utility technicians who need fast, reliable phase and rotation verification on motors, compressors, generators, and three-phase conductors. Key Features Phase sequence detection — identifies live phase and sequence orientation of three-phase power sources and industrial equipment conductors to ensure proper installation Motor rotation function — identifies rotational direction of industrial equipment including motors, compressors, and generators Non-contact motor rotation — determines rotation of running single-phase and three-phase motors without the use of leads CAT III 600V rated — safe for use on distribution-level electrical systems Wide frequency range — 15Hz to 400Hz covers standard power and variable frequency drive applications LED display — clear, fast visual indication of phase sequence and rotation results CE and CETLUS certified — meets international and North American safety standards Complete kit included — tri-colored banana leads, alligator clips, 9V battery, and soft carrying case Specifications Attribute Detail Part No. 5124 Type Phase Sequence & Motor Rotation Meter Voltage Rating CAT III 600V Phase Voltage Range 90V AC – 600V AC Frequency Range 15Hz – 400Hz Display LED Temperature Rating 0– 40°C Dimensions 123mm x 71mm x 29mm Weight 2 lb Compliance CE, CETLUS Accessories Included Tri-colored banana leads, alligator clips, 9V battery, soft carrying case Quick Decision Guide Need to verify three-phase sequence before energizing equipment? — The 5124 detects live phase and sequence orientation on three-phase power sources Need to check motor rotation direction? — Both contact and non-contact rotation detection are built in Working on running motors without access to leads? — The non-contact feature determines rotation without connecting leads Working on VFD or non-standard frequency systems? — The 15–400Hz range covers variable frequency drive applications Need internationally certified equipment? — CE and CETLUS compliance covers both European and North American requirements Frequently Asked Questions What is phase sequence and why does it matter?Phase sequence refers to the order in which the three phases of AC power reach their peak voltage. Incorrect phase sequence can cause motors to run in reverse, potentially damaging equipment or creating safety hazards. The 5124 verifies correct sequence before energizing. How does the non-contact motor rotation feature work?The non-contact feature allows the meter to determine the rotational direction of a running single-phase or three-phase motor without connecting test leads — useful when lead access is restricted or the motor is already running. What voltage range does the 5124 support?The 5124 measures phase voltage from 90V AC to 600V AC and is CAT III 600V rated for safe use on distribution-level systems. What accessories are included?The kit includes tri-colored banana leads, alligator clips, a 9V battery, and a soft carrying case. What certifications does the Greenlee 5124 carry?The 5124 is CE and CETLUS certified, meeting international and North American electrical safety standards.
