The ZYMM1 series Molded Case Circuit Breaker (MCCB) represents a cutting-edge innovation in electrical protection devices, incorporating international design and manufacturing technologies. This series is categorized into L-type (standard), M-type (higher breaking capacity), and H-type (current limiting) based on rated ultimate short circuit breaking capacity (Icu). Key features include a compact and small form factor, exceptional breaking capacity, minimal arcing distance, and robust anti-vibration properties, making it suitable for a wide range of applications on land and marine environments.
This circuit breaker is engineered for use in AC power distribution networks operating at 50Hz, with a rated insulation voltage of 800V and a rated working voltage of up to 690V. It supports rated currents of up to 800A, providing reliable protection against overloads, short circuits, and under voltage conditions. Additionally, it safeguards motors during infrequent starts by preventing overload, short circuit, and voltage deficiencies. The product strictly adheres to the IEC60947-2 standard, ensuring high performance and safety in diverse industrial settings.
Customization options are available to meet specific client requirements. Structure design and production cover components such as static contacts, movable contact pieces, clips, holders, and operational mechanisms. For appearance, choices include frame color combinations in black, gray, white, or dark gray, along with branding elements like company names, logos, type parameters, trace codes, and certifications such as CCC, CE, CB, or TUV. This flexibility allows for tailored solutions that align with various industrial standards and aesthetic preferences.
