CDM6S-800M/3348 500A Fixed Rear-Terminal Molded Case Circuit Protection Device
The CDM6S-800M/3348 500A fixed-type molded case protection device is engineered for industrial power distribution systems, featuring optimized structural configuration and modular design. Suitable for 500A rated current applications, its main body utilizes high-strength composite engineering materials combined with precision die-casting technology, achieving compact dimensions (XXXXXXXXX mm) while enhancing mechanical durability and insulation performance.
The rear-terminal connection design maximizes front-panel accessibility in distribution cabinets, enabling efficient multi-circuit arrangements within confined spaces. The 3P4L (3348 configuration) structure provides simultaneous monitoring of three-phase currents and neutral line status, integrating three-stage protection characteristics including overload long-time delay and short-circuit instantaneous tripping, with operational time accuracy maintained within ±5%. The innovative double-break contact system coupled with arc-quenching technology delivers breaking capacity up to XXkA level, ensuring rapid circuit interruption during fault conditions.
User-centric design elements include a synchronized position indicator window and operating handle mechanism, allowing direct visual confirmation of device status. Modular accessory slots facilitate post-installation expansion with auxiliary functions such as alarm contacts or shunt trip modules. With post-installation IP65 protection rating, the unit withstands challenging environments containing dust or moisture. Silver-nickel alloy composite contacts maintain stable resistance values after 20,000 mechanical operation cycles.
Ideal applications encompass manufacturing plant main distribution boards, commercial complex power rooms, and rail transit auxiliary supply systems requiring high-current protection. Installation requires minimum XXmm heat dissipation clearance and utilizes dedicated mounting rails for precise positioning. Recommended maintenance intervals range 3-5 years depending on operational environment, with internal arc chamber condition verifiable through inspection windows.
