The CHNAILE DZ47LE-63-4P Residual Current Miniature Circuit Breaker (MCB + RCCB) is designed for comprehensive protection in modern electrical distribution systems. This 4-pole breaker integrates overload, short-circuit, and leakage protection into one compact unit, offering enhanced safety for residential, commercial, and industrial environments.
Built with a 63A rated current, 6kA breaking capacity, and 400V 3-phase application, the DZ47LE-63-4P is ideal for main distribution boards, equipment control circuits, and leakage-sensitive loads. The device features a highly reliable electromagnetic + thermal trip mechanism and a residual-current module that rapidly disconnects power when detecting abnormal earth leakage, effectively preventing electric shock and fire hazards.
Engineered to meet GB/T16917.1, IEC, and other international standards, this breaker ensures durability, stability, and precise operation even under frequent switching or harsh environments. The ergonomic test button allows users to check leakage protection at any time, ensuring continuous system safety.
As a global supplier, CHNAILE supports OEM/ODM customization, including current ratings, leakage values, casing colors, terminal styles, label design, and packaging. Our intelligent automated production lines guarantee consistent quality, fast delivery, and competitive pricing for international distributors and brand owners.
Whether used in distribution boxes, industrial control cabinets, generator systems, building projects, or international retail markets, the DZ47LE-63-4P is a versatile and reliable protective component designed for modern electrical safety.
