FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering, in particular to emergency shutdowns of electrical equipment when exposed to high temperatures. The effect is achieved by the simultaneous use of the mechanism of differential and automatic shutdown of phases and the zero N shutdown mechanism, the generator of fire extinguishing aerosol (FEA) together with the electric igniter of FEA and the initiating temperature-sensitive device and the shutdown temperature-sensitive device located in the zone of exposure to heat that occurs when operation of the fire-extinguishing aerosol generator module (FEA); an initiating temperature-sensitive device and a shut-off temperature-sensitive device that are connected in series with each other, a FEA module actuation sensor, a smoke sensor, a thermal igniter capable of starting the FEA module without starting an electric igniter, a DIN-rail mounting unit, which is a slot for a DIN-rail located on the back side of the device case, in which a latch-mount is installed to fix the case on a DIN rail.
EFFECT: increasing the efficiency of primary fire extinguishing with an increase in the efficiency of preventing the spread of fire in a confined space.
