Abstract
An electric cutout includes a fuseholder in which a fusible element is mounted, a conducting element pivotally mounted to the lower end of the fuseholder and having a pair of trunnions disposed within a pair of spaced jaws on which a pair of guide surfaces are respectively mounted for cooperation with complementary guiding surfaces of arcuate configuration on the conducting element so that rotation of the fuseholder and conducting element about the trunnions may be effected in such manner that the trunnions are securely held against the bight portions of the jaws thereby to prevent rocking action of the fuseholder during closing movement thereof, an ejector latching element pivotally mounted on the conducting element and arranged to eject the fusible element upon rupture thereof and also arranged to engage a part of the fuseholder so as to prevent relative movement between the conducting element and the fuseholder, a U-shaped contact fixed in position adjacent the jaws and arranged to engage opposite surfaces of the conducting element so as to form a low impedance contact therebetween, and yieldable latching means fixed in position and arranged for engagement by latch elements form…
