РДП-UEТМ®-3000
- The relay is intended to supply a control signal to turn off a high-speed circuit breaker of the type WAB-UETM®-28, WAB-UETM®-49 when the main circuit current exceeds the value of the setpoint current of the specified direction.
- Relay RDP-UETM®-3000-UHL4 – polarized
- In terms of overall and connecting dimensions, the relay fully coincides with the unpolarized RDS-3000 relay.
