Arc extinguishing cover of molded case circuit breaker83
Product Description
This arc-extinguishing chamber housing assembly utilizes a precision molding process to create an integrated plastic shell structure, significantly improving dimensional accuracy and structural sealing. This optimizes the protective performance of the arc-extinguishing system from the source, effectively blocking arc spatter and high-temperature erosion, preventing arc damage to the core components inside the arc-extinguishing chamber. The precision-molded plastic shell structure ensures more even stress distribution, reducing operational wear and deformation risks, and significantly lowering the probability of core component failure. This dual approach of protection and structural design extends the service life of the circuit breaker's core components, reducing equipment maintenance frequency and replacement costs, and meeting the long-term stable operation requirements of various industrial-grade circuit breakers.
Composition
2 housings + 4 arc-damping meshes + 2 housing partitions + 8 screws M2.9×8. The housings and housing partitions are made of PA66 T303 20GF V0 GY steel, and the arc-damping meshes are made of galvanized steel sheet SGCC.
