Bimetal: Actually, it contains three metals iron, copper, cadmium, galvanized. Three metals with different coefficients of thermal expansion, bending cause thermal Pick reflect and making the breaker disconnect. This is the most import parts of the circuit breaker. The Bimetal is the use of different materials under different breaker amperage.
Coil: It's the important parts for the reaction of the Magnetic Trip. It's always 9 ring. As a matter of fact, the number of Coil with Different Amperage.For example, 1A reaches over 100 ring, and 63A is used to 56 ring. The Diameter Thickness is also different for Amperage.
Action Contactor(Sliver Point): It's the main point for the Reaction of Trip. Under normal conditions, keeping closed. When overload and short circuit, It will be breaking.
Arc Chute: Playing a role in destroying the arc. Generally tend to produce a large number of Moving and Static Contactor from the contactor, arc, even emerge spark.
