Product Description
Incorrect phase sequence within a three phase system is called phase reversal fault. Phase reversal usually occurs as a result of mistakes made during equipment installation, maintenance, or modifications to the facility power system. If the phase order or sequence is incorrect, the motor will rotate in the wrong direction and could lead to equipment damage, failure and/or personal injury.
Phase sequence test plugs quickly allow for inspection of phase rotational direction within seconds.
- GREEN lamp lights: phase sequence is correct
- RED lamp lights: phase sequence is wrong
- GREEN & RED lamps light: one phase is missing
Verifies correct phase sequence to ensure clockwise motor rotation. Confirms presence of all 3 phases to prevent ‘lost phase’ failures.
