Abstract
The present disclosure is related to a peak current limiting apparatus of the present disclosure comprising a trigger element serially connected between a power supply source and the load, diverting a fault current to other paths connected in parallel when the fault current exceeding a threshold is generated, a main contact switch serially connected between the trigger element and a load, a driving coil connected in parallel with the trigger element, and generating a repulsive force in response to the fault current to detach a contact point of the main contact switch, and a peak limiting impedance element serially connected between a connection node between the trigger element and the main contact switch and the driving coil, and limiting a first peak level of the fault current flowing through the driving coil to a predetermined level.
