UNI-T UT261B Phase Sequence and Motor Rotation Indicators

Description

Advanced Solutions For Three-Phase Electrical Diagnostics Worldwide

In modern electrical engineering and industrial maintenance, precise three-phase power diagnostics are an essential part of minimizing downtime, protecting equipment, and ensuring safe operation. The UNI-T UT261B Phase Sequence and Motor Rotation Indicator stands at the forefront of this critical field, offering professionals a robust, easy-to-use instrument for determining phase sequence, missing phase presence, and motor rotation direction. Whether facilitating the commissioning of large industrial equipment, troubleshooting electrical panels in complex infrastructures, or providing preventive maintenance in high-demand environments, the UT261B delivers accurate and reliable results quickly. The UNI-T UT261B is engineered with the specific needs of field engineers, electricians, and plant maintenance teams in mind, supporting seamless operations across diverse electrical installations.

Dedicated For Electricians, Installers, And Maintenance Technicians

Applications for the UNI-T UT261B extend well beyond generic voltage checks. This device is a tool of choice for professionals installing and servicing three-phase motors, generators, pumps, and power distribution systems. During equipment installation, the UT261B verifies correct phase sequencing, a crucial step for ensuring motors spin in the intended direction, preventing hazardous reverse operation and expensive damage. In routine maintenance, technicians use the UT261B to detect missing phases, which can indicate wiring faults or upstream supply issues—early identification of these problems prevents costly downtimes or catastrophic electrical failures. The ability to show phase sequence and missing phase via highly visible LED indicators, as well as rotating motor direction, makes this model an invaluable asset on any worksite handling three-phase energy.

Comprehensive Features For Broader Measurement Needs

The UT261B is more than a phase and rotation detector; it integrates a powerful assortment of modern electrical test features. The device supports AC voltage measurement from 90V to 600V, covering most three-phase equipment globally. It operates within a 15Hz to 400Hz frequency range, which means it can handle applications from traditional power grids to variable-frequency drives in automated plants. The device also offers a robust working current rating—consuming less than 3mA—so it places minimal load on the circuit under test. The device comes equipped with high-quality test leads fitted with alligator clips and protective tubing, ensuring safe and secure connections to terminals, even in high-traffic or cramped environments. Such accessories empower hands-free operation, protect both user and device, and enhance measurement stability.

User-Focused Design For Reliable Field Operation

Field reliability and convenience are built into every detail of the UT261B. Its bright red and grey enclosure increases visibility on busy worksites, while the ergonomic, lightweight design (only 180g) makes it a breeze to transport and operate—even with one hand. The device survives drops from up to 2 meters, meaning it withstands harsh industrial and construction environments. Its compact size (123mm x 71mm x 29mm) ensures it fits comfortably in toolkits and pockets, always on hand for quick diagnostic tasks. Powered by a standard 9V battery (included), the UT261B provides long operational life, and the well-designed battery compartment enables rapid replacement with no lost time during critical jobs. These qualities draw on decades of UNI-T design experience, always centered on the real-world needs of technicians.
