CDM1-125M/2300 40A Molded Case Circuit Breaker Product Introduction (English Version)

The CDM1-125M/2300 40A molded case circuit breaker is designed for low-voltage distribution systems, suitable for AC power networks with 50/60Hz frequency and rated voltage up to 400V. Featuring modular construction, this device provides reliable overload and short-circuit protection for distribution lines while supporting conventional motor control applications.

The product integrates a high-strength engineering plastic housing with precision-engineered contact assemblies, achieving optimal balance between mechanical durability and electrical performance. Its contact system incorporates a quick-break mechanism that reduces arcing duration, complemented by a multi-barrier arc chamber design to enhance current interruption capability. The optimized operating mechanism ensures smooth handle action with clear position indication through a visible status window.

Functionally, the breaker combines bimetal thermal tripping with electromagnetic instantaneous release mechanisms, delivering responsive protection against overload and short-circuit conditions. Designed for continuous operation at 40A rated current, its instantaneous trip setting allows reasonable adjustment according to specific application requirements. The terminal block features anti-loosening design, compatible with conductors up to 35mm² for both copper and aluminum cables.

The housing utilizes impact-resistant composite material with textured surface treatment to improve insulation properties. Internal thermal management is enhanced through optimized ribbed structures that promote heat dissipation, maintaining stable temperature rise during prolonged operation. Its compact footprint achieves approximately 15% space saving compared to conventional models, facilitating standardized installation in confined spaces.

This circuit breaker finds typical application in industrial switchgear, commercial building power distribution systems, and infrastructure electrical networks, providing effective protection against abnormal current conditions. Manufacturing processes implement rigorous quality control measures with automated assembly of core components to ensure parameter consistency. Routine maintenance should include periodic inspection of contact wear and mechanism mobility to maintain long-term operational reliability.
