This instrument is a motor rotation tester & 3 phase detector.
The KS3 is a device allows you to determine the rotation direction of a 3 phase motor by turning the motor shaft manually, as well as to check the phase sequence (positive, negative) and open phase condition of 3 phase lines.
Safety design that complies with IEC61010-1 CAT. III 500 V.
Motor rotation direction testable before connection of the power supply.
Phase sequence and open phase checking of three-phase lines.
Bright LED indicators.
Magnets on the back of the main unit allow it to be fixed on a distribution board and other metallic objects.
