DETAILED DESCRIPTION

DWB02.. & PWB02..

TRMS active power monitoring relays for 3- phase balanced systems.
They can be used for monitoring the actual load of asynchronous motors and other symmetrical loads, as well as the power consumption by of system.
Start/stop input allows to use a manual switch to start and stop the system, without 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 function can be used to avoid relay operation when not desired (maintenance, transitions).
The LED's indicate the state of the alarm and the output relay
