The reclosing time is the interval of time between the energizing of the opening release (e.g. opening coil) and the instant when the contacts touch in all poles during a reclosing cycle. If the differences in operating times (closing and opening time respectively) between poles are small and can be neglected, the following approximative formula can be applied: Reclosing time = Opening time + Arcing time + Dead time + Pre-arcing time
