ALF10K Series Miniature Circuit Breaker
Product Details
Product Descriprion
Engineered for global residential, commercial, and industrial electrical systems, the ELECO ALF10K Series Miniature Circuit Breaker (MCB) delivers flexible, reliable overcurrent and short-circuit protection with dual breaking capacity options of **6kA and 10kA**. Fully manufactured and tested in compliance with the IEC 60898-1 international standard, this series covers complete pole configurations including 1P, 2P, 3P, and 4P, with wide current ratings ranging from 0.5A to 63A and optional B, C, and D trip curves to suit lighting, general power, motor, and inductive load applications.
Featuring a durable compact body, universal dual terminal design, and standard 35mm DIN rail mounting, the ALF10K MCB ensures fast installation, stable conductivity, and long-term operational safety. Certified with CE, CB, and RoHS, the series supports smooth customs clearance and meets regional grid requirements for Middle East, African, Southeast Asian, and global markets.
Available in both standard 6kA and high-performance 10kA fault current resistance, the ALF10K series allows B2B clients—including electrical distributors, OEM panel builders, construction contractors, and electrical engineering companies—to select cost-effective or high-grade protection solutions according to project specifications. All units are factory-direct supplied with consistent quality, flexible OEM/ODM private labeling services, customizable packaging, and reliable 3-year factory warranty, ideal for large-volume wholesale, project bidding, and standardized panel assembly production.
