RS PRO TM-604 Phase Rotation Tester, CATIII 1000V, CATIV 600V, 400Hz Max, 600V ac Max with RS Calibration

Introducing the RS PRO 3 Phase / Motor Rotation Tester, ideal for phase sequence testing and three-phase motor installation and maintenance applications. This high-quality tester can quickly and reliably identify the phase sequence of three-phase electrical systems, as well as indicate normal or reversed phases as well as loss of phase. It also has the added feature of being able to check motors for rotation direction, determining correct connections. Designed to be durable and hardwearing, this rotation tester is ideal for use in a wide range of environments, with easy operation and offering the most essential features that are necessary for routine maintenance and system troubleshooting applications.

Phase rotation testers use incredibly useful portable devices that have been designed to check the direction of phase rotation in motorised machinery as part of routine maintenance to prevent damage to expensive machinery and equipment due to the incorrect rotation direction. The result is often identified by an LED light, making it quick and easy to see the result, especially in busy working environments and the tester can often check in both clockwise and counter-clockwise directions. Phase rotation testers are ideal for use in industrial and commercial environments like:

• Engineering


• Production and assembly lines


• Manufacturing and fabrication


• Warehouses and goods in/out
