UNI-T UT261A Phase Sequence Indicator

UNI-T UT261A Phase Sequence Indicator in Sri Lanka

Battery-Free 3 Phase Rotation Tester for Panel Checks

The UNI-T UT261A Phase Sequence Indicator shows the rotation order of a three-phase supply and warns you when a phase is missing. It helps electricians and maintenance engineers in Sri Lanka confirm wiring before connecting motors or machinery. Browse our full range of phase sequence indicators in Sri Lanka.

Results appear on an LCD, and the tester draws power from the circuit under test, so there is no battery to replace. The housing is built to survive a 2-meter drop, which suits daily site work.
