BE1-32R, BE1-32O/U, Directional Power Relay
These relays provide versatility and control in protecting machines against reverse power flow, underpower, and overpower conditions.
Benefits
- Accurate protection provided by real power measurement.
- Wide variety of available input options to meet system requirements, including single phase and three phase configurations.
- Timings can be tailored to the application with instantaneous-, definite-, and inverse-timing characteristics.
- Flexible pickup is continually adjustable over a wide range.
- Minimized CT and PT costs as a result of low sensing burden.
- Reduced battery load with low burden power supply.
- Accurate, repeatable, and reliable operation.
- Simple HMI provides clear and intuitive settings for easy configuration.
- LED targets provide clear annunciation of status.
- Easily perform in-case system and device tests using test paddles.
