Main distribution board
Power distribution is a system consisting of a Main Distribution Board (MDB), Sub Main Distribution Boards (SMDBs), and Final Distribution Boards, through which electrical energy is transmitted via branches to reach the end user.
The infrastructure market requires a dedicated range of switchboards where every aspect of construction, installation, and maintenance contributes to project profitability. Uninterrupted and safe electrical supply is essential for such installations, and our product range of main distribution boards offers the perfect solution.
An MDB is an enclosure housing fuses, circuit breakers, and ground leakage protection units, responsible for distributing electrical power to multiple individual circuits or consumer points. Electrical energy is received from the transformer or an upstream panel. An MDB typically includes one or more incoming power sources, main circuit breakers, and residual current or earth leakage protection devices, depending on client requirements. It consists of a free-standing enclosure, bus bar system, MCCBs, metering, support equipment, and necessary current transformers. The panels are assembled systematically with separate incomer and outgoing sections.
