CDM3-63F/4300B Molded Case Circuit Breaker Product Introduction (English Version)
The CDM3-63F/4300B molded case circuit breaker is a core protection device designed for low-voltage distribution systems. Featuring modular architecture, it delivers rapid circuit interruption for overload and short-circuit protection. With a rated current of 63A, this product is suitable for AC 50Hz/60Hz networks up to 400V, providing reliable power management solutions for industrial control systems, building electrical installations, and infrastructure applications.
Constructed with high-strength engineering plastics combined with metal components, the housing demonstrates excellent heat resistance and mechanical durability. The contact system employs specially alloyed materials and dual-breakpoint technology to enhance arc extinguishing efficiency. The four-pole (4300B) configuration meets neutral line protection requirements in three-phase four-wire systems, adaptable to various panelboard installations.
Precision coordination between electromagnetic and thermal trip mechanisms ensures accurate long-delay overload protection and instantaneous short-circuit response. The ergonomic operating handle provides clear ON/OFF position indication, with optional remote status monitoring interfaces. Anti-loosening terminal design securely accommodates conductors up to 35mm².
This circuit breaker is suitable for overcurrent protection in general distribution circuits, motor control circuits, and lighting systems. Typical applications include commercial buildings, manufacturing plants, and public facilities. The compact construction optimizes panel space utilization while maintaining high breaking capacity and extended service life. Regular functional verification and proper selection based on operational conditions are recommended to ensure system safety.
