SEW 890PR Safety Phase Sequence / Rotation Detector

● The 890 PR is a Non-Contact phase detector
with flashing LEDs and a beeping buzzer to
show the detection of AC 3-phase sequence.
● Two functions in one unit : open phase and
phase sequence detection.
● Convenient brightness switch to make the
indication visible in dim areas or sunlight.
● Back cover magnets which attach the instrument
to the AC distribution panel offer easy
measurement.
● 3-Phase AC 70 to 1000V is fitted for detection.

● Conductor size: 1~35mm
● Detect frequency range is from 45 to 65Hz.
