English Introduction
The CDM6S-63M/3200 40A Molded Case Circuit Protection Device is designed for low-voltage distribution systems, operating at 400V with a rated current of 40A. Its primary function is to ensure electrical system stability and equipment safety by rapidly responding to abnormal conditions such as overloads and short circuits.
Constructed with high-strength engineering plastic housing, the device combines insulation properties with mechanical durability. Internally, it integrates a precision electromagnetic trip mechanism and high-conductivity contact system, effectively reducing contact resistance while enhancing current-carrying capacity. The compact structure allows for DIN rail mounting, optimizing cabinet space utilization. The optimized breaking capacity enables swift circuit interruption during short-circuit events, minimizing energy dissipation. The arc extinguishing chamber s unique design contributes to extended service life and reduced maintenance needs.
This product is suitable for circuit protection in commercial buildings, industrial plants, and public infrastructure, compatible with motors, lighting systems, and general-purpose loads. The bimetal thermal trip technology enhances overload protection sensitivity, while the electromagnetic trip mechanism achieves millisecond-level response accuracy. The ergonomic operating handle provides tactile feedback for manual switching and status verification.
Safety features include multi-layer insulation isolation to reduce electric shock risks, with flame-retardant housing meeting general industry requirements. The fully enclosed structure offers dust and moisture resistance, operable in environments ranging from -25℃ to +70℃. Modular design facilitates quick replacement to minimize downtime. Routine maintenance should include terminal tightening checks and contact surface cleaning to ensure long-term reliability.
