InstallationImportant Planing ConsiderationsTransportation Switchgear UnitsDouble-Front InstallationsEnvironmental Conditions For SwitchgearSafety Against Arcing FaultsThe minimum clearances between switchgear and obstacles specified by the manufacturer must be taken into account when installing low-voltage switchgear (Figure 1). The minimum dimensions for operating and servicing corridors in accordance with IEC 60364-7-729must be taken into account when planning the space requirements (Figure 1, Figure 3). Where: 1. Minimum height of passage under covers or enclosures. 2. Attention:Above the panels, some space specified by the manufacturer MUST be free from obstacles to allow the pressure relief vents to open in the event of an arcing fault. Where: 1. With switchgear fronts facing each other, the space requirements only account for obstruction by open doors from one side (i.e. doors that don’t close in escape direction). 2.

Switchgear - Wikipedia

In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply. The earliest central power stations used simple open knife switches, mounted on insulating panels of marble or asbestos. Power levelsGet price
