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
