ZYD SM852B phase rotation indicator, 60–600 V, 20–400 Hz, LED + buzzer

Checks phase presence and rotation direction of a 3-phase supply. 60–600 V AC, 20–400 Hz, LEDs + sound, alligator clips. The SM852B is used when connecting motors, pumps, compressors and generators to confirm that the U-V-W sequence is correct. A continuous tone means correct rotation, an intermittent tone means a missing phase. Housing 72×72×30 mm, 246 g.
