An exhaust control device for use with a circuit interrupter includes a casing having a first expansion chamber and a second expansion chamber that are operationally disposed upstream of a heat sink and a damper, with the second expansion chamber being in fluid communication with the first expansion chamber and being in register with an inlet of the casing. The first expansion chamber extends between the inlet and the heat sink. The heat sink is a porous member that is annular in cross-section and includes a central cavity formed therein, the second expansion chamber being disposed in the central cavity. The first and second expansion chambers are configured to separate a blast of gases from the circuit interrupter into first and second pressure waves that sequentially travel through the heat sink and the damper, which reduces the peak intensity of the blast, extends its duration, and reduces its ionization level.

A shorting system, which eliminates persistent arcing faults in power distribution equipment, includes a first shorting switch having separable contacts, an actuation input and a fuse electrically connected in series with those contacts. A second shorting switch includes an actuation input and separable contacts, which are electrically connected in parallel with the series combination of the fuse and the first shorting switch contacts. A detection circuit includes one or more arcing light sensors and an actuation circuit. The light sensors detect arcing fault light and the actuation circuit responsively outputs a first trigger signal to the first shorting switch actuation input to close its contacts. For a persistent arcing fault, which is not eliminated by the first shorting switch, a predetermined time after the first trigger signal, the actuation circuit responsively outputs a second trigger signal to the second shorting switch actuation input to close its contacts.

A fuse mounting assembly includes an epoxy-bonded glass-fiber core that is surrounded by a resilient sleeve having a number of radially extending members. Attached to an end of the core is a first mounting bracket and attached to another end of the core is another mounting bracket. Each of the mounting brackets is connected to a fuse which is structured to protect a power circuit.

The present invention presents a multimedia signal distribution device that implements the Electronics Industry Association (EIA) "Node Zero" standard for a Consumer Electronics Bus (CEBus) signal distribution network. The preferred embodiment of the present invention comprises a block frequency conversion loop that is combined with other conventional electronic devices to accomplish the multimedia signal frequency conversion, filtering and distribution functions required of the ideal Node Zero device set forth in the EIA CEBus standard. The present invention preferably implements the CEBus block frequency conversion, input and output band-pass filtering, and signal amplification requirements by a block frequency conversion loop comprised of the following components which process the internal signal block in the following series order: (a) passive first low-pass or band-pass filter; (b) a 1000 MHz first frequency mixer; (c) an intermediate frequency (IF) filter; (d) a 38 dB signal amplifier; (e) a selectable second frequency mixer and (f) a tunable second low-pass or band-pass filter 11. Optionally, a broad-band quadrature signal phase shifting device may be implemented in conjunction with a signal coupling balun transformer at the input and output, respectively, of the first frequency mixer. This quadrature phase shifting improves the filtering of the internal signal block after the quadrature outputs have been shifted by the first frequency mixer to an intermediate frequency (IF) signal range.

An arc fault detector turns on an electronic switch connecting a power distribution cable to ground thereby actuating a cable limiter to isolate the power distribution cable in response to an arc fault even though the arc fault itself does not create a low enough impedance fault to actuate the cable limiter directly. The electronic switch can be a sacrificial low cost silicon controlled rectifier which is destroyed by the ground fault it creates as long as the let-through current of the cable limiter is below the explosion current of the SCR. A single arc fault detector and SCR which fails as a short circuit can be used to actuate cable limiters at both ends of a short power distribution cable fed at both ends, or preferably separate protection can be provided adjacent both cable limiters.

A trip mechanism for a fuse includes a trip unit disposed within an elongated housing of the fuse, and a processor. The trip unit includes a fuse element and an actuator for severing the fuse element. The processor is in electrical communication with the trip unit, and is adapted to monitor electrical current. Responsive to the processor detecting a predetermined prescribed electrical current, the processor is adapted to signal the actuator to sever the fuse element. The processor is programmable to selectively adjust the predetermined prescribed electrical current, thereby enabling the fuse to have a plurality different current ratings.
