Phase alternation indicators SEM DT-902, DT-901, etc.

Phase change indicators are used to determine the correct phase sequence in three-phase electrical systems, which is necessary for safe and reliable operation of the equipment. They are used in the installation, commissioning and maintenance of electrical equipment such as electric motors and drives to avoid damage and ensure the correct direction of their operation.

Models: DT-901, DT-902.
