Abstract
A solid state power controller is automatically reset if an overload trip occurs during a start-up delay period. If an overload trip occurs during load starting, the SSPC remains tripped for a reset delay period, and thereafter the SSPC is automatically reset, thereby allowing the starting process to continue by heating a lamp filament, accelerating a motor, etc., without indicating a system fault to an operator. At the expiration of the start-up delay period, the SSPC no longer automatically resets in response to an overload condition.
