Over Current Relay


  • BH System has the dedicated Relays that are installed and operated in the Ring Main Unit on the distribution network or the Circuit Breaker for multi-circuit.
  • The Relays basically perform protection functions on phase & ground Overcurrent, and allow user modification on the operation properties.
  • They are possible to interface with RTU for remote control and monitoring with a dedicated controller.
  • Shape and assembles of the Relay and the attached components may be changed according to a design of distribution equipment such as RMU. The following picture is an example of the Relay and the Controller being installed together with the RMU.
