【English Introduction】
The CDF1-20 series molded case circuit breaker is an intelligent electrical protection device specifically designed for low-voltage distribution systems. Featuring surface-mounted installation and an integrated protective enclosure, it is suitable for circuits with AC 50Hz and rated voltage up to 400V. With a rated current of 10A and 3-pole configuration, this product effectively controls power supply circuits in three-phase systems, providing reliable line protection for industrial control systems, commercial buildings, and residential power distribution applications.
The compact modular design combines surface-mount technology with space-saving advantages, significantly improving installation efficiency. The protective enclosure, molded from high flame-retardant engineering plastics, achieves IP40 protection level, effectively preventing dust intrusion and accidental contact while ensuring stable operation in humid or dusty environments. Equipped with precision electromagnetic trip mechanism and thermal bimetal protection system, it delivers rapid response to overload and short-circuit faults, with breaking capacity up to 6kA for reliable fault current interruption.
Silver-alloy composite contacts with low resistance and arc-erosion resistance work in synergy with optimized arc-extinguishing chambers to enhance electrical durability. The visible switching status indicator and dual operation modes (manual quick-break and remote control compatibility) ensure flexible application across various scenarios. Ideal for motor protection, lighting distribution, and equipment power control, it particularly suits electrical cabinet upgrades with space constraints.
Maintenance-friendly design allows easy enclosure removal for contact inspection and cleaning. Regular trip testing is recommended to maintain protection sensitivity. Through structural optimization and material innovation, this product achieves energy-efficient operation while maintaining safety performance, making it an optimal choice for modern power system management.
