Reliable Phase Rotation and Motor Testing

The UT261 Series Phase Sequence and Motor Rotation Indicators are essential tools for HVAC technicians and electricians working with 3-phase electrical systems. These devices provide a fast, safe, and accurate way to determine phase rotation and motor direction, ensuring that machinery runs correctly and preventing damage caused by reversed wiring. Whether you are commissioning a new site or troubleshooting existing switchboards, these indicators provide the confidence needed for high-stakes electrical work.

Available in two distinct models, the UT261 series caters to different operational needs. The UT261A offers battery-free operation with a clear LCD readout, while the UT261B is a battery-powered unit featuring LED indicators and specialized motor rotation detection. Both units are built to withstand the rigours of industrial environments with a 2-metre drop-proof rating and a high CAT III safety classification.

Why It Matters

Incorrect phase sequence can lead to catastrophic motor failure or hazardous equipment operation in commercial HVAC systems, such as industrial fans and compressors. By using a dedicated indicator like the UT261, you eliminate the guesswork and ensure every 3-phase installation is electrically sound before power is applied, protecting both the equipment and the technician.

• Wide Frequency Range: Operates reliably across a frequency spectrum of 15Hz to 400Hz.
• Phase Detection: Easily identifies missing phases and correct sequence rotation.
• Low Current Consumption: Designed for efficiency with a working current of less than 3mA.
• Visual Clarity: Features easy-to-read LCD (UT261A) or bright LED indicators (UT261B) for instant feedback.

Applications

• ✓ Verifying 3-phase power supply sequence in commercial switchboards.
• ✓ Testing motor rotation direction before final connection to avoid mechanical damage.
• ✓ Identifying missing phases in complex HVAC control wiring.
• ✓ Commissioning industrial pumps, air handling units, and large condensers.

Tradie Pro Tip

When testing motor rotation on disconnected motors using the UT261B, connect the leads and rotate the motor shaft manually in your intended direction. The LEDs will show you the resulting sequence, allowing you to terminate your cables correctly the first time without needing to 'bump' the motor under live power.
