What is a Distribution Box? A distribution box, or DB box, is a circuit breaker enclosure. It is a vital part and central hub of any electrical system. The hub distributes electrical power from a single input source to various circuits throughout a building. Our intelligent and mechanical boxes in the area of power and data distribution offer modular solutions for all voltage levels and at the same time optimize functionality - for maximum efficiency with maximum safety. As a pioneer of the power and data distribution of the future, LEONI always keeps. Inside, several key components work together to ensure safe and efficient power distribution: Circuit Breakers: These devices protect circuits by cutting off power during overloads or short circuits, preventing damage.
