UT262A/C are clamp type non-contact phase detectors. Users do not need to be in contact with high-voltage, reducing risk of electrical shock to electricans and other professional personnels. Beside phase sequence detection, UT262 series can also be used for live wire detection, simple electrical inspection, phase identi?cation, missing-phase judgment, and wire breaker searching. It is a perfect tool for phase sequence detection, motor mounting, and wires maintenance.
