Carlo Gavazzi Power Factor Monitoring Relay, 3 Phase, SPDT, DIN Rail

3 Phase Load Guard Monitoring Relay. Carlo Gavazzi DWB01 ; PWB01 series of precise TRMS power factor monitoring relays deisgned for use with 3 phase systems. Suitable for monitoring the actual load of asynchronous ; symmetrical loads where proportional load ; power factor is present. DWP01 ; PWB01 series of monitoring relays feature a start/stop input allowing use of a manual switch to control the motor without any auxiliary device. Another great feature of the DWB01 ; PWB01 series is a latch function which enables the relays to be kept energised even after the alarm has finished. DIN rail (DWB01 series) and plug-in module (PWB01 series) variants available TRMS load guard relays for 3 phase balanced applications Power factor measurement within set parameters Programmable latching or inhibit features 1 - 30 Seconds knob adjustable power ON delay LEDs for relay, alarm ; power indication
