## Summary description

Unit UT261B is a phase sequence and motor rotation direction tester designed for verifying phase order and the direction of three-phase motors. Operates on 90–600 VAC and frequencies from 15 to 400 Hz. Useful for electricians and maintenance technicians when commissioning, troubleshooting or confirming correct motor wiring and rotation, reducing installation errors and downtime.

## Long description

The Unit UT261B is a professional-grade phase sequence and motor rotation direction tester engineered for precise electrical diagnostics in three-phase systems. This handheld device allows technicians to quickly verify the phase sequence of power lines and determine the rotation direction of three-phase motors, ensuring that equipment is wired correctly before full operation. With a broad operating range of 90 to 600 VAC and a frequency response between 15 and 400 Hz, it provides reliable performance across a wide variety of industrial and commercial electrical environments.
Advantages
This tester offers significant benefits for electrical maintenance and installation by providing clear, non-contact indication of phase status. Its robust design ensures durability in demanding work conditions, while the intuitive interface allows for rapid testing without complex setup procedures. By accurately identifying phase order and motor rotation, the device helps prevent mechanical damage and operational failures caused by incorrect wiring, ultimately saving time and reducing maintenance costs during system commissioning or troubleshooting.
Suitable for
Verifying phase sequence in three-phase power distribution systems
Checking motor rotation direction during installation or maintenance
Troubleshooting electrical wiring issues in industrial machinery
Commissioning new three-phase electrical equipment
When it may not be suitable
This device is not designed for use on low-voltage circuits below 90 VAC or high-voltage systems exceeding 600 VAC. It is intended specifically for three-phase applications and will not function on single-phase AC or DC power systems.
Key specifications
Operating voltage: 90–600 VAC
Frequency range: 15–400 Hz
Phase sequence indication: Yes
Motor rotation indication: Yes
Power source: Battery operated
How to use
To use the device, connect the provided test leads to the corresponding phases of the power source or motor terminals according to the color-coded markings. Once connected, the tester will indicate the phase sequence or motor rotation direction through its visual display. Ensure that the test leads are securely attached to the terminals to obtain an accurate reading and always follow standard electrical safety protocols when working with live circuits.
What to consider before purchase
Verify that your electrical system operates within the 90–600 VAC range
Ensure the device is compatible with your specific three-phase motor configuration
Check if the frequency of your power supply falls within the 15–400 Hz range
Usage recommendations
Always inspect the test leads for any signs of damage or wear before each use. Ensure the device is kept clean and dry, and store it in a protective case when not in use to maintain measurement accuracy and longevity.
