A protection relay device includes a housing and a fuse unit. The fuse unit includes a connection conductor, an input conductor connected to the connection conductor and receiving an external power, a fuse connected to the connection conductor, and an external device connection conductor connected to the fuse on a side opposite to the input conductor, and to which an external device is connected. A short-circuit induction conductor is provided on at least one of the input conductor on a side opposite to the fuse and the flapper portion, the short-circuit induction conductor protruding toward the other of the input conductor and the flapper portion.

A power distribution panel for distributing power to a plurality of components. A modular frame may removably attach in an aperture of a side of a chassis. A first module may be removably attached in an opening of the modular frame. A second module, different from the first module, may be removably attached in the opening of the modular frame.

The invention relates to a box (10) including a pair of fuses (14) intended for protecting an electrical apparatus. Each of the fuses (24, 26) has a first end (28, 32) and a second end (30, 34), said fuse box (10) comprising a pair of output terminals (46, 50) coupled with the first ends (28, 32) and a pair of input terminals (80, 86) coupled with the second ends (30, 34). The box further comprises at least one other pair (16) of fuses, each of the fuses (25, 27) of said at least one other pair having other first (36, 40) and second (38, 42) ends, and another pair of input terminals (64, 70) coupled respectively with the other second ends (38, 42). The other first ends (36, 40) of said at least one other pair of fuses are coupled respectively with the terminals of said pair of output terminals (46, 50).

A fuse holder provides a safe device for connecting fuses to a three-phase busbar device. Each phase includes a corresponding load conductor and line conductor mounted within a housing. A mechanical lock is provided for each phase that locks a knife of the fuse to one of the conductors for the phase. In a further aspect, the fuse knives are frictionally locked within the housing. In both the mechanical lock and frictional lock, a release mechanism is provided that can be activated by a screwdriver to release the fuse knives from the fuse holder. In another aspect, certain conductors are provided with heat dissipation wings that contact the housing to dissipate heat generated by current flowing through the conductor.

An electrical assembly may include a bus bar assembly, a fuse connected to the bus bar assembly, a contactor connected to the bus bar assembly, a bracket connected to the bus bar assembly, and/or a cooling member connected to the bracket such that the fuse is indirectly connected to the cooling member via the bus bar assembly and the bracket. A method of operating an electrical assembly may include controlling the contactor to provide current from a power source to a load, generating heat via the current flowing through the fuse, conducting the heat from the fuse to the bus bar assembly, conducting the heat from the bus bar assembly to the cooling member, and/or dissipating the heat via the cooling member.
