CDM1-250L/3300 200A Molded Case Circuit Breaker (MCCB) with Rear-Mounted Connection
The CDM1-250L/3300 200A molded case circuit breaker is a core protective device developed for low-voltage distribution systems. Featuring optimized structural design and multi-level safety mechanisms, it provides precise protection against circuit overload and short-circuit faults. With a rated current of 200A, this product is suitable for main circuit protection in commercial buildings and industrial plants.
Adopting a modular design, the compact structure effectively saves installation space. The main housing is integrally molded from high-strength engineering plastics, demonstrating excellent heat resistance and impact resistance. Three-phase independent arc-extinguishing chambers combined with premium conductive materials enhance breaking capacity. The contact system undergoes special surface treatment to reduce contact resistance and ensure long-term stability.
The rear-mounted connection design simplifies installation procedures while accommodating various wire specifications. The operating mechanism features an intuitive three-position indicator (Open/Closed/Tripped) and an independent energy-storage handle, delivering smooth operation torque and reliable contact movement. The product supports multiple accessory expansions, allowing flexible configuration of auxiliary contacts and alarm modules according to actual requirements.
Safety protection incorporates multi-layer isolation barriers to ensure effective separation between live parts and operators. The transparent protective cover enables visual status inspection, while the built-in quick-release mechanism responds to abnormal currents within milliseconds. The product supports both vertical and horizontal installation orientations to adapt to different switchgear layouts.
Key advantages include:
- Adaptive thermal-magnetic trip mechanism for precise protection
- Ergonomic operation interface with clear status indication
- Robust mechanical structure with 20,000+ electrical endurance cycles
- Maintenance-friendly design with detachable functional modules
- Wide ambient temperature tolerance (-25°C to +70°C)
This circuit breaker provides reliable system protection for power distribution networks, motor control centers, and other scenarios requiring stable current control. Its balanced performance in safety, durability, and operational efficiency makes it a practical solution for modern electrical systems.
