Product Description
Ordering key
DWB 02 C M48 10A
DWB02 and PWB02 are precise TRMS active power monitoring relays for 3- phase balanced systems. They can be used for moni- toring the actual load of asynchronous motors and other symmetrical loads, as well as the power consump- tion by of system.
Start/stop input allows to use a manual switch to start and stop the system, with- out the need of an auxiliary

device.
The advantage of using the latch function is that the alarm status can be kept even after the end of the alarm condition. Inhibit func- tion can be used to avoid relay operation when not desired (maintenance, tran- sitions).
The LED's indicate the state of the alarm and the output relay.
