Phase Sequence/Motor Rotation Tester (480403)

Product Announcement from Flir Commercial Systems

Phase Sequence/Motor Rotation Tester (480403)-Image

Problem: You just had a motor serviced or you bought a replacement motor. You're ready to connect it. What is the critical task you must perform to ensure the correct operation of your new/repaired motor's connected load? You must determine the motor's correct rotation.

Don't be fazed by phase sequence!

Solution: The durable and compact Extech 480403 is ideal for determining phase sequence on 3-phase systems, confirming phases are live, and checking rotation direction on motors and rotating plant equipment. The Extech sequence/rotation tester also features the added safety of a built-in non-contact rotation detection sensor. This 2-in-1 meter checks both phase sequence and motor rotation.

• Indicates rotation direction of the motor
• Determine rotation of a motor without contact
• Ensures that motor does not get damaged from incorrect wiring
• 40 to 600VAC rated test range for testing phase orientation of three phase power sources over 2 to 400Hz frequency range
• LEDs indicate phase orientation (clockwise or counter-clockwise) and whether each of the three phases is live
• Durable housing is double molded
• Easy to open alligator clips with wide jaws
• Complete with cable and three large color coded alligator clips, pouch case, and 9V battery

Typical Operation Tasks

  • Determine Phase Rotation Direction
  • Check Motor Turn Direction (contact method)
  • Check Motor Turn Direction (non-contact method)
  • Related task: Magnetic Field Detection
