Blokset Low Voltage Switchgear

The Blokset switchgear can be applied in all locations requiring highly reliable low-voltage power supply systems, including distribution centers, power control centers, etc. It is widely used in industrial sectors such as metallurgy, paper-making, manufacturing, and mining, as well as in commercial and infrastructure sectors like shopping centers, hotels, airports, and ports. Its basic framework is assembled from standard prefabricated components, available in various specifications to form frames of different sizes. The switchgear consists of four distinct compartments: the busbar compartment, component compartment, outgoing cable compartment, and auxiliary compartment. A single switchgear can contain up to 40 modules, and the cabinet is available in two types: fixed partition and drawer type.
