Product Overview
The molded case leakage protection circuit breaker CDM6LI-250L/4300B 160A 1/3/5 delay 1 is designed for power distribution system protection, suitable for circuits with AC 50Hz/60Hz and rated voltage up to 400V. Featuring a compact plastic housing, it integrates earth leakage protection, overload protection, and short-circuit protection to enhance electrical safety. Its core components include a zero-sequence current transformer, electronic trip unit, and operating mechanism, enabling rapid fault detection and current interruption. The product is widely used in industrial plants, commercial buildings, and infrastructure projects for distribution boards or control panels, facilitating circuit segmentation and fault isolation.615
Key Features
With adjustable tripping characteristics (1/3/5 delay 1), this breaker allows customization for diverse load profiles. The earth leakage function monitors residual current and trips upon reaching preset thresholds; overload protection relies on thermal-magnetic tripping to prevent equipment damage from sustained overcurrents; short-circuit protection responds within milliseconds to high-current faults, minimizing arc risks. The modular design supports auxiliary contacts and shunt releases for system expansion. A visible handle indicates ON/OFF status, with manual/auto reset options.418
Specifications
Rated current of 160A and breaking capacity of 4300B make it ideal for medium-capacity distribution lines. The 4P (3-phase+neutral) configuration ensures comprehensive protection, backed by over 10,000 mechanical cycles and extended electrical durability. The flame-retardant housing and optimized arc-extinguishing structure enhance operational safety. Operating temperatures range from -5°C to +40°C, suitable for most indoor environments. Compact dimensions support DIN rail or fixed mounting.19
Applications
Ideal for main/distribution circuits in commercial complexes, manufacturing facilities, and data centers where safety is critical. Typical uses include backup protection for motors, lighting systems, and transformers to mitigate risks from insulation failures or aged wiring. It also suits photovoltaic systems or temporary power installations requiring leakage monitoring.1220
