Product Overview
The DELIXI CDM3-250S/3300 molded case circuit breaker is a high-performance protection device designed for power distribution systems, with a rated current of 250A and 3P poles. It is suitable for circuits with AC rated voltage up to 1500V. The product features a square extended hand-operated lever (300MM length), enabling safe and convenient manual operation in switchboards. Its core functions include overload and short-circuit protection, utilizing a thermal-magnetic trip unit for precise current control. With a breaking capacity of 35kA, it ensures stable operation of electrical equipment. The compact dimensions (806080mm) and lightweight design (approx. 1.5kg) make it ideal for space-constrained installations.1421
Design Features
The CDM3-250S/3300 adopts a robust gray molded case housing, resistant to corrosion and suitable for industrial environments. The square extended lever optimizes operational torque, allowing easy switching even in densely packed panels. The air-based arc extinguishing system quickly interrupts fault currents while minimizing arc effects. Front-mounted terminal wiring ensures flexible installation for diverse power distribution layouts. The 250A frame current rating matches its breaking capacity, guaranteeing reliability in high-voltage and high-current scenarios.41321
Applications
This breaker is widely used in low-voltage distribution systems for industrial plants, commercial buildings, and infrastructure projects, particularly in motor protection, transformer outlets, and main switchgear protection. Its thermal-magnetic tripping characteristic adapts to resistive, inductive, and capacitive loads. The extended lever design is ideal for scenarios requiring frequent manual operations, such as maintenance or emergency power cuts. The product is available in single-unit or bulk packaging (1 unit/box, 4 boxes/carton) for efficient logistics and storage.146
