The focus of the studies is on the influence of contact material production parameters, and the
electrical life for breaker interaction of material combinations used for the low voltage protection devices. The
influence of contact button manufacturing process will be scrutinized by practical validation as switching
performance of AgC material with different size and fiber orientation will be compared. The paper represents
guideline for contact button manufacturing process selection for low voltage protection devices as well as which is the
suitable for the low voltage circuit breaker is also described by the EET testing.
