LV distribution boards, part of the electrical distribution system, securely distribute low-voltage power to facility circuits. Integrated with ACBs and MCCBs, they provide protection from overloads, short circuits, and others. You must make safety your top priority when working with low voltage distribution boxes. Like the foundation of a building, their reliability remains invisible until it fails. That's where IEC 61439 comes in. We will be glad to provide you with extensive sup-port from initial information, planning, configuration and. Distribution boxes can be broadly categorized by their voltage level, application environment, and primary function.
