DESIGN OF THE REGULATORS OF THE THERMO ELECTROMAGNETIC PROTECTION DEVICE OF THE AUTOMATIC SWITCH Russian patent published in 2023 - IPC H01H71/10 

FIELD: electric power, electrical engineering.

SUBSTANCE: present invention relates to electric power and electrical engineering and is intended to protect electrical circuits from overload currents and short circuits. The design of the circuit breaker cover provides for the presence on the outer plane of sockets with shelves for the installation of thermal release regulators or electromagnetic release regulators, has rectangular protrusions and grooves, and there are two protrusions on the inner plane limiting the rotation of the regulators in a given sector. The design of the heat release regulator provides for the presence of rectangular protrusions on the surface, a rectangular protrusion on the cylindrical surface of the outer side of the regulator level with its end face, an executive organ in the form of a cylinder above the end of the cylindrical surface. The design of the electromagnetic release regulator provides for the presence of rectangular protrusions on the surface, a rectangular protrusion on the cylindrical surface of the outside of the regulator flush with its end, an executive organ in the form of a protrusion with a curved working surface.

EFFECT: increasing the service life and reliability of both the thermo-electromagnetic protection unit of the circuit breaker and the circuit breaker as a whole.
