英文介紹：
The DZ20L-160/4340B molded case residual current circuit breaker is a high-performance protection device specifically designed for low-voltage distribution systems. It operates in circuits with AC 50Hz and rated working voltage up to 400V, providing rapid detection and interruption of leakage currents, overloads, and short-circuit faults. Featuring a modular structural design, this product combines operational convenience with safety and reliability, making it suitable for power system protection in industrial plants, commercial buildings, and public infrastructure.
With a rated current of 160A and residual current operating value of 500mA, the device effectively monitors leakage current variations in circuits. Upon detecting leakage currents exceeding the preset threshold, the breaker can interrupt power supply within 0.1 seconds, significantly reducing electric shock risks and fire hazards. The integrated 24V DC auxiliary control power supply supports external signal expansion, enabling seamless integration into automated control systems for intelligent power management.
The housing is molded from high-strength engineering plastics, offering excellent insulation and impact resistance. The multi-stage arc extinguishing system ensures rapid fault current interruption and effective arc suppression. A clear mechanical status indicator window and manual switching mechanism simplify device commissioning and maintenance. The four-pole (3P+N) configuration is compatible with three-phase four-wire distribution networks, delivering comprehensive circuit protection.
