CDM1-630L/3300 500A Molded Case Circuit Breaker
The CDM1-630L/3300 500A molded case circuit breaker is a high-performance circuit protection device designed for low-voltage distribution systems. With modular architecture and reinforced structural engineering, it delivers reliable overload and short-circuit protection for industrial and commercial power environments. Rated at 500A operational current, the product is suitable for AC 50Hz networks up to 690V, meeting diverse power distribution and control requirements across multiple application scenarios.
Key advantages manifest in three dimensions: Firstly, the optimized contact system employs silver alloy composite materials combined with double-breakpoint interruption technology, significantly enhancing arc quenching efficiency to ensure rapid circuit interruption during short-circuit events. Secondly, the compact structural design maintains high mechanical strength while reducing installation footprint, supporting both horizontal and vertical wiring configurations with standard 35mm rail mounting compatibility. Thirdly, the user-centric interface features clear ON/OFF indicators and energy storage status display, complemented by adjustable tripping characteristics for precise circuit management.
Technical highlights include three-tier protection mechanisms: The thermal-magnetic trip unit coordinates overload time-delay protection with instantaneous short-circuit protection, delivering advanced breaking capacity. The arc chamber integrates multi-layer metal grids with high-temperature resistant insulation materials to effectively suppress arc propagation. The enclosure utilizes high-strength engineering plastics with excellent impact resistance and flame-retardant properties, achieving IP40 protection grade. The product also supports various functional accessories such as shunt releases and auxiliary contacts, allowing flexible control function expansion according to operational requirements.
This circuit breaker is widely applied in industrial plant distribution cabinets, commercial complex main power systems, and new energy equipment control panels. It proves particularly effective for motor protection, transformer output terminals, and main circuit protection. Through rigorous factory testing protocols, the product maintains stable performance across -25℃ to +70℃ temperature ranges. The fully enclosed structure effectively prevents dust ingress, ensuring long-term operational reliability.
