Its primary purpose is to ensure safe and efficient power distribution while providing protection via fuses or circuit breakers against overloads and short circuits. Distribution boxes are built with durable materials, typically metal or high-grade plastic, designed to endure. A Distribution Box, commonly known as a DB Box, serves as the central point for safely distributing electrical power from a main supply to multiple downstream circuits. SMART DISTRIBUTION BOXES FOR FLEXIBLE BUILDINGS. What is a Distribution Box? A distribution box, sometimes referred to as a distribution board or panel, is a critical. Interconnect/distribution box systems provide in-flight experiences to commercial airline passengers worldwide. Our reference designs and integrated circuits enable innovation on performance and size, weight and power (SWaP) reduction in IFE monitors and other peripherals.
