Description

The Miniature Circuit Breaker-UNB3-80 Series is an advanced electrical safety device designed to automatically switch off electrical circuits during abnormal conditions, such as overloads or faults. This exceptional MCB boasts a high frame level with a 1P+N double breaking point in a compact 18mm width and a remarkable breaking capacity of up to 6kA. Engineered with precision, it features a terminal with error-protected terminal blocks and an innovative contact position indicating window for enhanced safety.

With its current-limited contact system and magnetic blow-out type arc extinguishing device, this circuit breaker effectively protects equipment from large short circuit currents while improving the arc extinguishing ability, thus ensuring optimal breaking capacity. The shell and function keys are made from PA66 nylon, which is flame retardant, high temperature resistant, and impact resistant, offering durability and reliability in challenging environments.

Designed with an innovative appearance and reasonable structure, the Miniature Circuit Breaker-UNB3-80 Series includes multiple patent protections for added confidence. It also features overload, short circuit, and leakage protection functions, making it a comprehensive solution for electrical safety.
