CDM6S-400M/3360 400A Molded Case Circuit Protection Device is a high-performance solution designed for modern power distribution systems, suitable for 400A rated current networks. This integrated protection unit combines overload protection, short-circuit protection and isolation functions through modular design, effectively enhancing system safety and operational reliability.
The housing adopts composite structure with high-strength engineering plastics and metal components, providing excellent mechanical strength and heat resistance with IP40 protection rating. Equipped with intelligent tripping mechanism and three-stage protection curves (long-time delay, short-time delay, instantaneous trip), it allows precise parameter settings according to practical requirements. The silver-alloy contact system with double-break design reduces contact resistance, improves conductivity efficiency and extends service life.
Compatible with AC 50/60Hz power systems up to 690V, this device can be installed in various distribution cabinets, control panels and electrical equipment. The energy-storage operating mechanism ensures reliable switching operations with clear "ON/OFF" position indicators. Supporting multiple installation methods, it adapts to both vertical/horizontal mounting configurations with 35mm standard rail or fixed panel compatibility.
Technical parameters include breaking capacity up to 50kA, meeting demanding circuit protection requirements. The visual status indicator window enables quick operational status assessment. For diversified application scenarios, optional accessories are available including auxiliary contacts, alarm contacts and shunt release modules.
