Using LED indicators, you can immediately determine the phase sequence, motor rotation direction, and any phase loss. Ideal for checking correct wiring before commissioning equipment.
The device operates in the 90–600 V AC and 15–400 Hz range, making it suitable for both standard and more demanding applications in industry, maintenance, and installations.
The lightweight body (180 g), dimensions 123 × 71 × 29 mm, and power from a 9V battery (6F22) make it easy to carry. The package also includes 3 leads with alligator clips and a case for safe storage.
The Uni-T UT261B phase sequence tester makes it easy to verify correct wiring of a three-phase supply before putting equipment into operation. Clear LED indicators provide information about phase sequence, possible phase loss, and motor rotation direction, so you can quickly identify wiring errors even during routine checks.
Thanks to the low operating current < 3 mA, operation is safe and convenient. Compact dimensions and 9V battery power make it a practical tool for every electrician’s bag.
