Abstract:
A solid state motor starter comprising:a first electrically conducting bus bar adapted to receive an external current carrying conductor from a power source at an input end;a second electrically conducting bus bar adapted to receive an external current carrying conductor connectable to a motor at an output end of the motor starter;a pair of solid state power switching devices clamped between the first and second electrically conducting bus bars; anda discrete electromagnetic switching relay having an electrical input and an electrical output forming a bypass current path, the electrical input connectable to the external current carrying conductor from the power source through the first electrically conducting bus bar, and the electrical output of the switching relay connectable to the output end of the motor starter, the discrete electromagnetic switching relay mounted such that the bypass current path is in linear relation with the second electrically conducting bus bar, thereby providing a linear current path through the solid state motor starter when the discrete electromagnetic switching relay is switched to relay power from the power source to the motor.
