Abstract

An improved three-phase disconnector, said disconnector comprises: three horizontally mounted current limiting fuses, each of said fuses individually being connected to one phase of a three-phase power supply line and further comprising three corresponding striker pins adapted to axially move in an operative first direction upon detection of an overcurrent fault; three sliding contacts coupled to said three striker pins, each of said sliding contacts adapted to axially slide in said first direction upon activation of said corresponding striker pin; three stationary contacts placed collinear to said three sliding contacts; winding wires being placed in between said sliding contacts and said stationary contacts such that a single wire is passed through said spaced-apart region between a corresponding sliding contact and a corresponding stationary contact; spring loaded plungers adapted to receive said winding wires; and vertical insulation tubes adapted to receive said spring loaded plungers when they fall down.
