Breaking Characteristics
The breaking characteristics (*1) of the distribution board circuit protectors must be the long-time delay type
and must be equivalent to or slower than the D (IEC/EN60898-1) shown in
If the distribution board's circuit protectors have a breaking characteristic that is faster than D, the breaker
may trip when a power supply unit in the storage system fails. When the breaker trips, a shutoff occurs on
multiple power supply units connected to the same connection line as the failed power supply unit.
