Product Description Ordering key
DWA 01 C M48 5A
DWA01 and PWA01 are pre- cise over or under cos ϕ monitoring relays.
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.
