CDM3-250S/3320 200A Molded Case Circuit Breaker Product Introduction (English)
The CDM3-250S/3320 200A molded case circuit breaker is a professional electrical protection device developed for modern power distribution systems. Suitable for AC 50Hz/60Hz networks with rated operational voltage up to 690V, it delivers reliable overload and short-circuit protection for industrial, commercial, and infrastructure applications.
Featuring an innovative modular construction, the breaker s high-strength thermoplastic housing provides excellent dielectric strength and mechanical robustness. The multi-contact system with arc chute configuration ensures efficient arc extinguishing capability. With 200A current rating, this 3-pole device optimally protects main circuits and high-capacity branch lines in power distribution systems. The spring-operated mechanism guarantees swift and consistent switching operations, while compact dimensions allow flexible vertical/horizontal mounting in limited spaces.
Visual position indicators and manual operating handles enable clear status monitoring. The trip-free mechanism immediately interrupts fault currents regardless of handle position. Modular accessory slots support functional expansions such as shunt releases or auxiliary contacts. Internal components undergo specialized treatment to maintain stable performance within -35℃ to +70℃ ambient temperature range, demonstrating strong adaptability in humid or dusty environments.
Typical applications include: Main switchgear protection in factory substations, floor distribution cabinets in commercial buildings, DC-side protection for photovoltaic systems, and motor control centers in port machinery. The product s selective coordination capability helps minimize power outage scope during system faults. User-friendly features include tool-free installation clamps, color-coded terminals, and ergonomic handle design to streamline installation and maintenance processes.
Engineered for durability, the breaker s silver-alloy contacts and corrosion-resistant hardware ensure long service life. The balanced magnetic circuit design effectively reduces power loss during normal operation. This solution combines robust
