应用场景
DZ20Y-100/3310 50A广泛应用于工业、商业及建筑配电领域，如工厂配电柜、矿山设备、楼宇电力系统等。在电动机保护场景中，可为额定电流225A以下的鼠笼型电机提供过载和短路保护。产品适应多种环境条件，包括高温（-5℃至40℃）、潮湿或多尘场所，但需配合防水箱或防尘箱使用以延长寿命。51017
产品优势
该断路器以Y型为基础设计，结构稳定且维护便捷。其斥力限流触头系统可在大电流故障时快速限流，降低设备损伤风险。相比同类产品，它在分断速度与操作寿命方面表现均衡，性价比突出。透明外壳版本（部分型号）便于直观检查内部状态，进一步提升运维效率。91221
Product Overview
The DZ20Y-100/3310 50A moulded case circuit breaker is designed for low-voltage distribution systems, suitable for circuits with AC 50Hz and rated voltage up to 380V. It provides reliable protection against overload and short-circuit faults, while enabling infrequent circuit switching. Featuring a compact structure, the breaker integrates a robust operating mechanism and quick-break contacts, ensuring safe operation of electrical equipment. Its high-flame-retardant plastic shell enhances durability and insulation performance.125
Technical Features
With a rated current of 50A and frame current of 100A, this breaker offers excellent breaking capacity. Its dual-protection trip unit accurately responds to overload and short-circuit conditions. The contact system rapidly separates under fault currents, minimizing arcing time. Manual operation is supported, with clear handle positions indicating "ON," "OFF," and other statuses for easy maintenance. The 3-pole (3P) design suits three-phase systems, and optional neutral pole configurations address specific safety requirements.2613
Applications
Ideal for industrial, commercial, and building power systems, the DZ20Y-100/3310 50A is commonly used in distribution cabinets, mining equipment, and facility power networks. For motor protection, it safeguards squirrel-cage motors below 225A. The product adapts to diverse environments, including high-temperature (-5℃ to 40℃), humid, or dusty conditions, though auxiliary enclosures are recommended for extended service life.51017
Advantages
Based on the Y-type design, this breaker ensures structural stability and ease of maintenance. Its current-limiting contact system swiftly mitigates high-fault currents, reducing equipment damage risks. Compared to peers, it balances breaking speed and operational longevity with cost-effectiveness. Transparent housing variants (select models) allow visual inspection for streamlined troubleshooting.91221
