The UT262E is a non-contact phase detector designed in a clamp-type configuration. This innovative design eliminates the need for direct contact with bare wires, minimizing the potential for electric sparks. This feature significantly reduces the risk of electrical shock for professionals such as electricians. The UT262E serves various purposes, including live wire detection, basic electrical inspections, phase identification, determination of missing phases, locating wire breakers, and discerning positive or negative states through both audio and visual indicators.

This device proves to be an ideal tool for tasks like phase sequence detection, motor installation, and wire maintenance. Its implementation enhances the safety of on-site testing, ensuring the well-being of operators and ultimately boosting overall productivity.
