The core functions of a DC MCCB are overload protection and short-circuit protection. When the current exceeds the rated voltage, the DC molded case circuit breaker will automatically trip to prevent equipment from overheating and damage. When a short-circuit fault occurs, the DC molded case circuit breaker will detect the huge current and trip within milliseconds, isolating the fault and protecting the solar system.
The product is made of flame-retardant materials, DC-specific arc extinguishing cover and silver point, and high-quality accessories to ensure product performance. The product's breaking capacity reaches 20KA, protecting your photovoltaic system.
