STATIC POWER’s Static Transfer Switch will transfer seamlessly to a secondary source if failure of the primary.
To avoid propagation of a current fault to the alternate source, iSTS will not transfer if a load is faulty. iSTS will inhibit any transfer till the fault is cleared.
If the fault is not cleared, iSTS protections will be actioned: the load and/or all loads connected to the iSTS will not be supplied.

Multiplying available sources and limiting the number of loads connected to one iSTS reduce System’s risk of failure
