At the heart of the DX4-30 high-breaking-capacity miniature circuit-breaker lies a sophisticated blend of components, including a robust plastic shell, an efficient operating mechanism, a precision-engineered contact-arc-extinguishing system, and a responsive tripping mechanism. The shell, crafted from a unique high-flame-retardant and high-strength plastic, ensures exceptional impact resistance while maintaining a lightweight profile. This innovative design promises durability and safety in every use.
The circuit breaker's operating mechanism is meticulously crafted from high-strength plastic materials, striking the perfect balance between sensitivity and reliability while minimizing rotational inertia. This design ensures an ultra-fast response time from the onset of a short-circuit fault to the activation of the tripping mechanism. The tripping mechanism itself is ingeniously composed of a bimetallic-strip overload-and-delay-tripping system alongside a short-circuit instantaneous electromagnetic tripping system. Complementing this system is the contact-arc-extinguishing technology, which employs expertly crafted arc-guiding angles and arc-extinguishing chambers to deliver outstanding current-limiting capabilities, enhancing safety and efficiency.
