In terms of material selection, considering the working environment of the circuit breaker, we offer a variety of base materials such as copper, copper alloy, stainless steel, and iron, and can perform surface treatments such as silver plating, tin plating, and zinc plating according to conductivity requirements. For example, the rivets used in the conductive circuit of the circuit breaker are made of high-purity copper and silver-plated, which increases conductivity by more than 30%; the rivets used for fixing the casing are made of highly corrosion-resistant 304 stainless steel, extending the service life of the equipment.
