This Wiha Rotational Field Indicator comes with an integrated phase display. The rotation direction as well as the live phases are reliably indentified with the help of an LED display. A crocodile clip included with the delivery allows a simple connection, e.g. with a motor terminal board. In combination with the included test tips, the rotation indicator from Wiha offers great testing flexibility. The rotational field indicator works with the mains voltage itself, so no batteries are required. According to the measurement category CAT III up to 1,000 V and CAT IV up to 600 V the rotation indicator offers maximum safety for working directly on the source of low voltage installations.
