FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering and energy and can be used for prompt emergency shutdown of electrical equipment when exposed to high temperatures, for example, in case of fire, as well as overload, short circuit. A distinctive feature of the patent is the simultaneous use in the composition of the product of the automatic phase shutdown mechanism and the zero N shutdown mechanism, the fire extinguishing aerosol generator (FEAG) together with the FEAG electric igniter and: heat generated during the operation of the fire extinguishing aerosol generator module (FEAG); an initiating temperature-sensitive device (t2) and a tripping temperature-sensitive device (t1) connected in series with each other; FEAG module actuation sensor; smoke sensor; a thermal igniter capable of starting the FEAG module without starting an electric igniter; node for mounting on a DIN rail, 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, in particular, such as an electrical panel, while simultaneously protecting against short circuits and overloads.
