Determining the direction of rotation in a three-phase power supply to check electrical connections? No problem with the Wiha rotation direction indicator with integrated phase indicator. Both the direction of rotation and the phases under voltage can be reliably identified using an LED display. The crocodile clip included in the scope of delivery enables easy connection, e.g. with a motor terminal board. Together with the supplied test tips, the Wiha rotation direction indicator offers great flexibility in testing. The rotating field direction indicator works with the mains voltage itself, so no batteries are needed. According to the measurement category CAT III (up to 1,000 V) and CAT IV (up to 600 V), the direction of rotation indicator provides maximum safety for working directly at the source of low-voltage equipment.
