Реле контроля последовательности фаз Caterpillar 4909982

A Phase Sequence Relay is designed to monitor the phase sequence of a three-phase electrical system. The phase sequence is the order in which the three phases of a system reach their maximum voltage. A phase sequence relay is used in switchgear to prevent damage to equipment caused by incorrect phase rotation.Attributes: • Detect the correct phase sequence of the incoming power• Manufactured to precise specifications and are built for durability and reliabilityApplications:A Phase Sequence Relay is used to prevent the machine from starting if the phase sequence is incorrect.
