Electrification is advancing across all industries – from electric vehicles and charging infrastructure to energy storage, aerospace, and fuel cells. As a result, the demand for reliable protection mechanisms in high-voltage systems is increasing.
Unlike conventional fuses, the APO Fuse operates actively. In the event of a short circuit or accident, the control unit sends a trigger signal to an integrated micro gas generator. Within milliseconds, the generator produces high pressure that drives a piston to mechanically sever the solid copper busbar. The resulting arc is safely suppressed in a dedicated extinguishing chamber. The outcome is a complete galvanic isolation in less than two milliseconds – with measured values as fast as 0.9 ms.
