The critical role of fire rated switchgear is to maintain the power to the vital equipment such as smoke extraction or ventilation fans to facilitate safe evacuation of buildings, car parks, or other public areas in the event of a fire. These switch-disconnectors are generally installed near the extraction fan for isolation of power supply and have been tested in conjunction with fan equipment to meet the stringent thermal requirements of fire safety and BS EN 12101-3.
