CZF-332 Phase Loss Sensor 1Z/1R with Contact Control
The phase loss sensor with contact control is designed to protect electric motors powered from a three-phase network in cases of voltage loss in at least one phase or voltage asymmetry between phases.
Application
This device protects motors from damage that may occur due to voltage loss or contact failure in the system. It also has the capability to monitor phase loss and asymmetry, which increases the safety of electric motor operation.
