The CDM3-125S/3300 125A plug-in molded case circuit breaker is a high-performance circuit protection device specifically designed for low-voltage distribution systems. Featuring modular construction and reliable short-circuit/overload protection functions, this product is widely applicable to industrial control cabinets, building power distribution systems, and equipment power circuits, delivering stable safety protection for electrical systems.
With its compact design optimized for space efficiency, the 125A rated current capacity meets general load requirements. The 3300 configuration provides three-pole circuit protection. The contact system employs special alloy materials combined with multi-arc extinguishing structures, significantly enhancing breaking capacity. Precision-adjusted operating mechanism ensures smooth closing and instantaneous trip response. The front panel features a visible mechanical status indicator for quick operational monitoring.
The plug-in installation design is a key advantage, allowing direct integration with standard busbar systems for rapid installation and replacement. The snap-fit mounting structure minimizes wiring work, enabling quick removal of the breaker body during maintenance to substantially reduce downtime. The enclosure utilizes high-strength engineering plastic with integrated molding technology, balancing insulation performance and structural integrity. Surface anti-corrosion treatment ensures reliable operation in humid or dusty environments.
Incorporating thermal-magnetic trip technology, the built-in protection mechanism provides accurate response to current variations. The bimetal strip and electromagnetic coil work in synergy to handle both sustained overloads and instantaneous short-circuit faults. All conductive components feature silver-plated contacts to reduce resistance and energy loss. The removable front cover facilitates wiring operations while maintaining safety standards.
Routine maintenance should include visual inspection of the breaker surface and terminal tightness, ensuring unobstructed ventilation. When the indicator shows tripped status, always eliminate circuit faults before resetting. Suitable for 50/60Hz AC networks with rated operational voltage up to 400V, professional electrician installation is recommended.
