DETAILED DESCRIPTION

DWA01CM… ή PWA01CM…

DWA01 and PWA01 are precise over or under cos φ monitoring relays, so it is the ideal solution to control different of the normal functions in pumps (dry running), belt systems and other functions far away from the human control.  
The relays monitor their own power supply voltage and the current of a balanced 3-phase system.
For current measure direct connection, 5A standard current transformers and MI CT can be used.
The LED's indicate the state of the alarm and the output relay.
