A remote control with a waterproof function, according to an embodiment of the present invention, includes a case including an upper case having a plurality of button holes and a lower case assembled to the upper case at a lower portion of the upper case, a printed circuit board PCB embedded between the upper case and the lower case, and a rubber keypad, which is embedded between the upper case and the lower case so as to mounted to surround the side portions of the PCB and has a plurality of buttons that pass through the plurality of button holes and barrier parts that come into close contact with the inner surface of the upper case and the inner surface of the lower case, where the upper case and the lower case come into contact with each other.

A method for preventing an electrical grid from failure in case of a temporary overvoltage includes providing an electrical grid line, a surge arrester and a disconnector device with a disconnector unit. The method further includes connecting the surge arrester at one terminal to the electrical grid line, connecting the surge arrester at its other terminal to a first terminal of the disconnector device, and connecting a second terminal of the disconnector device to ground potential. The method further includes interrupting the electrical connection in between the electrical grid line and the ground potential in response to a temporary overvoltage. The method further includes protecting the surge arrester from failure due to a thermal overload caused by the temporary overvoltage by operating the disconnector device before the surge arrester fails due to a thermal overload of the surge arrester.

A switching device is provided. The switching device includes a housing including a base and a switching device cover coupled to the base, a line side terminal positioned on a line side of the housing, a load side terminal positioned on a load side of the housing, wherein the line side is opposite the load side, a first terminal cover coupled to the switching device cover proximate the line side, and a second terminal cover coupled to the switching device cover proximate the load side, wherein the first terminal cover is movable between a closed position and an open position, wherein the first terminal cover is attached to said switching device cover in both the closed and open positions, and wherein the second terminal cover is attached to the switching device cover in both the closed and open positions.

A safety shutter of the present disclosure comprises: a base unit; a shutter unit; and a cam unit. The base unit is coupled to a cradle of an air circuit breaker, and a terminal connected to a main circuit passes through the base unit. The shutter unit is coupled to the base unit so as to be spaced apart at a predetermined interval, and accommodates the terminal in the space between the shutter unit and the base unit. The cam unit extends from the base unit and penetrates the shutter unit. The shutter unit deactivates insulation by exposing the terminal in the direction of the air circuit breaker when the air circuit breaker is inserted in the direction of the base unit.
