FIELD: electrical engineering and energy.
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, such as fire, as well as overload, overcurrent, short circuit, and electric current leakage. A distinctive feature of the invention is the simultaneous use of a differential phase shutdown mechanism and a zero N shutdown mechanism, a fire-extinguishing aerosol generator (EAG) together with an electric EAG igniter and an initiating temperature-sensitive device (t1) and a shutdown temperature-sensitive device (t2) located in the zone of heat exposure as part of the product. arising during the operation of the fire-extinguishing aerosol generator module (EAG); an initiating temperature-sensitive device (t2) and a tripping temperature-sensitive device (t1) connected in series with each other; EAG module actuation sensor; smoke sensor; a thermal igniter capable of starting the EAG module without starting an electric igniter; a DIN-rail mounting unit, which is a slot for a DIN-rail located on the back 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 electric current leaks.
