Extech 480403 Phase Rotation and Motor Tester - 3-Phase Sequence Indicator, 40V to 600V AC Range, Non-Contact Detection, 2 to 400Hz Frequency with Color-Coded Alligator Clips and Protective Pouch

Product Description The Extech 480403 is a must-have diagnostic powerhouse for every industrial electrician and maintenance technician. Incorrectly wiring a three-phase motor can lead to immediate equipment failure or hazardous mechanical reversals; the 480403 eliminates that risk by providing a clear, visual map of your electrical system's rotation. This 2-in-1 meter not only identifies the phase sequence of a power source but also features a unique non-contact motor rotation mode. By simply holding the device near a running motor, you can verify the rotation direction without ever stripping a wire or opening a terminal box. Shutterstock Explore Designed to perform in demanding environments, the 480403 supports a wide voltage range of 40V to 600V and handles frequencies from 2Hz to 400Hz, making it suitable for everything from standard commercial power to specialized high-frequency industrial drives. The unit is housed in a shock-resistant, double-molded casing and meets CAT III-600V safety standards for peace of mind during live testing. The kit comes complete with heavy-duty, color-coded alligator clips, a 9V battery, and a convenient carrying pouch to keep your tools organized. Whether you are installing new machinery or troubleshooting an existing HVAC line, the Extech 480403 provides the accuracy and safety you need to get the job done right the first time. From the Manufacturer Phase Sequence and Motor Rotation Tester has a 40 to 600V rated range for testing phase orientation of 3-phase power sources over a 2 to 400Hz frequency range. LEDs indicate phase orientation (clockwise or counter-clockwise) and whether each of the phases is live. In addition, it indicates rotation direction of the motor to ensure that it doesn't get damaged from incorrect wiring. Meter comes complete with cable and three large color coded alligator clips, pouch case, and 9V battery.

• VERSATILE 2-IN-1 FUNCTIONALITY: Take the guesswork out of complex electrical systems by determining both phase orientation of power sources and the rotation direction of motors. This essential tool helps prevent catastrophic damage from incorrect wiring.
• NON-CONTACT MOTOR TESTING: Safely determine the rotation direction of running motors without making direct contact. Simply place the meter near the motor housing and watch the bright LEDs confirm clockwise or counter-clockwise movement instantly.
• WIDE OPERATING RANGE: Designed for professional industrial environments, this tester handles 40V to 600V AC rated ranges across frequencies from 2Hz to 400Hz. It is the perfect diagnostic companion for HVAC systems, industrial pumps, and conveyors.
• RUGGED INDUSTRIAL BUILD: Survive the rigors of the job site with a durable double-molded housing and a CAT III 600V safety rating. The high-quality color-coded alligator clips feature wide jaws for secure connections on large terminal blocks.
• INTUITIVE LED INDICATORS: Get immediate visual feedback with clear LED status lights that show whether each of the three phases is live. The easy-to-read interface ensures you can identify phase sequence errors in seconds, even in dim lighting.
