A method to protect a circuit having at least a first circuit breaker, and a second circuit breaker arranged upstream of said first circuit breaker, said first circuit breaker having configuration settings selectable between a normal mode and an alternate mode, the alternate mode setting including a reduced energy let-through (RELT) mode setting having a RELT mode trip time delay. The method including determining if said first circuit breaker is configured in said RELT mode, determining a dynamic delay time for opening said second circuit breaker, wherein said dynamic delay time is based at least in part on said RELT mode trip time delay of said first circuit breaker, and triggering said second circuit breaker to open after said dynamic delay time has elapsed.
