摘要:
A first and a second pairs of projecting portions are provided in a cavity portion of a fuse mounting portion made of resin. An upper end surface of each projecting portion is tapered, so as to guide a pair of male terminals of a fuse sub-assembly toward a corresponding female terminals attached to the cavity portion, when the fuse sub-assembly is inserted into the cavity portion. A gap is formed between the fuse sub-assembly and the tapered upper end surfaces in a fuse-mounted condition, in which the fuse sub-assembly is in contact with a stopper portion of the cavity portion, in order to prevent contact failure caused by thermal shock.

A fuse block assembly includes a nonconductive base formed with pedestal surfaces attachable to terminals from a location above the base, while providing a clearance between the body of a fuse and the middle portion of the base when a fuse is installed.

A modular fuse carrier provides an insulating housing of standard form factor incorporating adapter bus bars having multiple mounting points for different fuse brackets at different separations. The adapter bus bars may be attached to connectors and/or bus bars in fixed configurations to allow standardization and pre-manufacture of electrical assemblies that remain amenable to a wide variety of different fuse types and capacities.

A fuse holder adapter for use with knife-blade fuse clips used with standard 600 ampere fuses in which the adapter comprises first and second metallic plates mounted in facing, spaced relationship on an insulator plate. The first and second metallic plates have respective first and third sections which are adapted to receive fuse clips to form fuse holders of different length and further have respective second and fourth sections formed as knife-blades and extending beyond the insulator plate so as to be able to be receivable in the knife-blade fuse clips used with the standard 600 ampere fuses.
摘要:
A modular switch-fuse unit is provided which can be engaged via terminals 26 with a busbar supply system. The unit is divided into a switch compartment 14 and a fuse compartment 16, the latter having an access door 36 which is normally blocked by operating handle 38 when in the "on" position. Handle 38 is provided with a semi-concealed latch 64 allowing access to the fuses 32 when live.

A circuit breaker for protecting an electric circuit contains a housing and an adapter having a receiving connector. The circuit breaker has two electrically conductive, substantially cylinder-shaped connection points which are positioned along an axis. Either the outer diameter of the connection points is between 5.0 mm and 5.3 mm and the maximum distance between the connection points is between 19.0 mm and 21.0 mm, or the outer diameter of the connection points is between 6.2 mm and 6.5 mm and the maximum distance between the connection points is between 30.5 mm and 33.0 mm.
摘要:
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.
