The autorecloser SMBRREC function provides high-speed and/or delayed autoreclosing for single or multi-breaker applications.
Up to five three-phase reclosing attempts can be included by parameter setting.

The first attempt can be single-, two and/or three phase for single phase or multi-phase faults respectively.

Multiple autoreclosing functions are provided for multi-breaker arrangements. A priority circuit allows one circuit breaker to close first and the second will only close if the fault proved to be transient.

Each autoreclosing function can be configured to co-operate with a synchrocheck function.
