CDM1-125M/3340 Molded Case Circuit Breaker Introduction
The CDM1-125M/3340 molded case circuit breaker is a high-performance protection device designed for low-voltage distribution systems. With 3-pole protection unit and modular structure, this product provides reliable overload and short-circuit protection under rated current 25A and rated voltage AC220V, suitable for power distribution and equipment protection in various electrical networks.
Featuring a high-strength engineering plastic enclosure, the breaker demonstrates excellent insulation performance and impact resistance. The silver-alloy contact system works in coordination with an optimized arc chute design, which enhances breaking capacity while minimizing arc hazards. The spring-operated mechanism ensures quick closing/opening operations, complemented by clear handle position indicators for manual control and status monitoring.
Equipped with a thermal-magnetic trip unit, the device employs bimetal strip and electromagnetic coil for precise current detection. The bimetal element activates delayed protection during overload conditions, while the electromagnetic assembly enables instantaneous response to short-circuit faults. This dual protection mechanism maintains reliable circuit protection with minimized false tripping risks.
Widely applicable in industrial control systems, commercial building distribution, and public facility power supply scenarios, the product is ideal for motor protection, distribution panel main switches, and lighting system controls. Standardized mounting dimensions support DIN rail installation, with comprehensive accessory options for easy system integration and maintenance.
Technical specifications include rated insulation voltage AC800V and adequate ultimate short-circuit breaking capacity. Contact endurance exceeds 20,000 mechanical operations and 10,000 electrical cycles. The IP40 enclosure protection rating ensures stable performance under various environmental conditions.
For optimal performance, periodic maintenance should include mechanism lubrication checks and surface cleaning. The trip indicator window provides clear fault notification, requiring circuit troubleshooting before reset operations. Optional auxiliary contacts are available for signaling function expansion based on application requirements.
This product embodies streamlined structural design with multi-layer safety considerations, delivering both compact dimensions and reliable protection characteristics. Its balanced performance makes it a practical solution for modern electrical protection needs.
