Air Circuit Breakers (ACBs): Used in main LV distribution boards for high fault interrupting capacity. The distribution box prevents that cascade — it receives power from the main supply, divides it into protected branch circuits, and isolates faults before they spread. Selecting the right type determines whether a facility runs without interruption or chases electrical faults through disorganized. However, the distribution of electrical energy comes with inherent risks. High voltages and currents, if not properly managed, can lead to system faults, equipment damage, fire hazards, and even fatal accidents. The five main benefits of putting a surge. In lightning protection, the surge protection device in distribution boxes plays a crucial role.
