These boards typically manage voltages of 220–240V and serve loads up to 63A or 100A. Suitable for commercial buildings, factories, or any facility with a 380–415V supply. These DBs distribute power across three live wires (L1, L2, L3) and require more complex load. A distribution board or distribution box is where the main power supply is distributed to multiple loads. And all the switching and protective devices are installed in the distribution box. Single Phase Distribution Box generally consists of Double Pole MCBs, Single Pole MCBs, and RCCBs. As a manufacturer and system provider, HUYU Electric offers a wide range of DB boxes tailored for different applications—from modular surface-mounted boards to IP66 weatherproof units for solar PV systems. To put it simply, a DB Box works like a traffic controller for electricity—it manages the. A distribution board (also known as panelboard, circuit breaker panel, breaker panel, circuit breaker, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit. Our distribution boards guide explains what they are, their uses and types, and how to connect distribution boards. It includes isolator, RCCB (Residual current circuit breaker) or RCD (Residual-current device) devices, protective fuses or MCB's (Miniature Circuit Breaker).
