Abstract: A fuse having a plurality of configurable thermal ceilings. The fuse includes a housing, a first conductive cap, a second conductive cap, a plurality of conductive elements extending through the housing, and a conductive connector that is electrically coupled to a conductive element. One or more conductive elements are electrically connected to the first conductive cap at any one time.

Abstract: An apparatus and method for locating and retaining a nut plate utilizing at least one peg having tapered, crushable ribs, dimensioned and configured to frictionally engage a corresponding aperture in the nut plate, thereby locating and retaining the nut plate until a bolt is threadedly secured to the nut plate.

Abstract: A circuit breaker has a magnetic trip assembly which can be adjusted to trip the breaker for low level overcurrents in the range of five to ten times rated current. The magnet trip includes for each pole of the breaker a helical torsion spring having one torsion arm which biases an armature against an adjusting bar to form a gap between the armature and a stationary magnetic structure in which magnetic flux strong enough to attract the armature and trip the breaker is induced by overcurrent. A second torsion arm of the spring has a first portion which bears against and slides along a pivot member carried by the adjusting bar to adjust the bias force applied to the armature by a given amount per unit travel of the adjusting bar over a low trip current portion of the range of travel of the adjusting bar.
