A fuse incorporates a fusible element assembly and an auxiliary fusible element assembly in a solid arc extinguishing material configuration. The fusible element assembly has a first operating characteristic and the auxiliary fusible element has a second operating characteristic different than the first operating characteristic. An installation adapter may be used to adapt a fuse to a non-standard mounting for the fuse. The installation adapter may include first and second adapter members that secure to the fuse to provide contacts having an appropriate spatial relationship to engage the non-standard mounting. A fuse and an installation adapter may be packaged as a kit.

An exhaust control device includes a wear indicator disposed within a housing of the exhaust control device. The wear indicator is arranged to be exposed to a flow of exhaust gas through the exhaust control device. The wear indicator has a first observable state indicative of remaining useful life of the exhaust control device. The wear indicator is responsive to a flow of exhaust gas through the exhaust control device to assume a second observable state indicative of the exhaust control device having reached the end of its useful life.

An improved fuse cutout is provided of the type having a fuse tube assembly that moves to a dropout position upon operation in response to a fault current or other overcurrent. These types of fuse cutouts include the pivotal mounting of the fuse tube assembly with respect to a support hinge with the fuse tube assembly being released for pivotal movement to the dropout position when the fuse cutout has operated. The fuse tube assembly includes a collapsible toggle joint that collapses upon operation of the fuse cutout. The improved fuse cutout includes additional dropout assistance that is provided via a resilient member operating between the components of the collapsible toggle joint to apply a force to assist the collapse of the toggle joint.

A mounting for a circuit interrupter is provided that facilitates the easy removal and insertion of the circuit interrupter. The mounting includes upper and lower terminal and support arrangements that cooperate with upper and lower device mounting studs of a circuit interrupter. The device mounting studs also function as electrical circuit connection points to connect the circuit interrupter in an electrical circuit via respective upper and lower contact assemblies of the mounting. The upper and lower contact assemblies include resilient retention facilities for providing suitable electrical contact forces when engaged with the device mounting studs. The upper and lower terminal and support arrangements retain the circuit interrupter within the mounting and are selectively operable to release the circuit interrupter for removal from the mounting. Each of the terminal and support arrangements include a latch arm that is moved to release the respective device mounting stud from a retained holding position to a latch release position. The mounting also includes a resilient guiding member that cooperates with one or more of the latch arms to retain the circuit interrupter in a latched released position after operation of the latch arm. The resilient guiding member includes a protruding arm that acts against the device mounting stud as the latch arm is moved outwardly to release the device mounting studs.

A retention arrangement for a circuit interrupter to ensure that ensures the retention of the circuit interrupter in its mounting. The retention arrangement cooperates with a latch member of the mounting for the circuit interrupter. Accordingly, the circuit interrupter is retained in its mounting even where the dimensions of the circuit interrupter may vary from the nominal specified dimensions.
