UNI-T UT261A 3-Phase Sequence and Phase Rotation Indicator – 40V–690V AC Electrical Tester in Pakistan

Overview

When installing industrial 3-phase motors, HVAC systems, or distribution panels, connecting phases incorrectly can cause costly motor reverse-rotation damage or equipment failure. Guessing wiring orientation is a major safety hazard. The UNI-T UT261A 3-Phase Sequence Indicator provides a professional electrical testing solution, designed to accurately determine 3-phase power sequence and detect missing phases safely across wide voltage ranges without requiring batteries.

Key Features

• Wide AC Voltage Detection: Capable of measuring and operating across a broad AC voltage span from 40V to 690V.

• Broad Frequency Range Support: Engineered to handle standard industrial power frequencies ranging from 15Hz up to 400Hz.

• Clear LCD Indication: Features an integrated LCD screen for instant visual display of phase sequence and missing phase status.

• Battery-Free Operation: Draws minimal operating current directly from the test lines, eliminating the need for replacement batteries.

• Rugged Job-Site Durability: Built to withstand accidental drops and impacts from a height of up to 2 meters.

Technical Specifications

Common Applications

• Motor & Pump Installation: Ensures correct phase sequencing before starting heavy 3-phase industrial motors and compressors.

• Electrical Panel Maintenance: Quickly identifies missing phases and live wiring faults during troubleshooting routines.

Note to customers: Always inspect test leads for insulation damage before connecting to high-voltage industrial circuits!
