A switching device of the switching module is connected in electrical series between the first and second module terminals and is configured to switch between an ON state for allowing electrical current through the electrical circuit and an OFF state for opening the electrical circuit to stop current flow therethrough. The circuit breaker has a first housing that houses the breaker mechanism therein. The switching module has a second housing that houses the switching device therein.

Abstract: A fault managed power method and system are provided, which includes a source, downstream component(s) and a power cable for delivering electrical energy, including electrical pulse(s) or DC current/voltage and electrical pulse(s), from the source to the downstream component(s). The cable is isolated from upstream and downstream noise or signals using low-pass filters, which are arranged upstream and downstream of the power cable. The method and system can measure electrical activity on the cable using an impedance sensor tank circuit; detect for an electrical disturbance on the cable corresponding to an occurrence of a fault resulting from body contact with the cable or other faults, based on the measurements from the sensor, when the pulses or the DC current/voltage and pulses are supplied to the cable; and in response to detection of the occurrence of the fault, interrupt the supply of electrical energy to the cable, via an upstream switch(es).

Abstract: In some embodiments, a method includes calculating costs associated with migration from a telecommunications infrastructure in a first configuration to the telecommunications infrastructure in a second configuration. The migration is based on a first infrastructure data and a second infrastructure data. The first infrastructure data is associated with the telecommunications infrastructure in the first configuration and the second infrastructure data is associated with the telecommunications infrastructure in the second configuration. A predictive migration model is generated based on the calculated costs, the first infrastructure data, and the second infrastructure data.

A detection circuit cooperates with the smoke or gas sensor and is structured to trip one of the circuit breakers in response to the detected smoke or gas emitted from overheated plastic or to annunciate the detected smoke or gas emitted from overheated plastic.

Abstract: An electrical distribution device that includes a terminal for providing a connection to a first conductor, a spring mechanism having a first end that is electrically connected to the terminal, and a second conductor electrically connected to one or more internal components of the device. The spring mechanism has a first condition and a second condition. In the first condition, the second end is electrically connected to the second conductor by solder. When the solder melts, the spring mechanism moves from to the second condition in which the second end is no longer electrically connected to the second conductor, thereby protecting the internal components from the fault condition that lead to the overheating. A condition indicator may also be provided for indicating a fault condition.

Abstract: As many as possible of the arc plates of an arc chute assembly have complimentary reverse compound curves to form between them gas flow paths for arc gas that discharge directly into a gas vent. Where the gas vent is not large enough, the remaining arc plates have a concave upward curvature forming additional gas flow paths that discharge smoothly into a vertical gas passage adjacent their trailing edges that extends upward to the gas vent.

Abstract: An improved circuit breaker includes a case, a movable arm, and a bumper retained within a receptacle formed on the case. The bumper is retained in the receptacle by a number of spaced ribs that engage certain portions of the bumper yet permit deformations of other portions of the bumper into an expansion region. By employing a bumper made of a material having a low coefficient of restitution, deformation of the bumper tends to dissipate the energy of a movable arm impacting the bumper. The bumper can be installed, removed, and replaced substantially without requiring the use of an adhesive. The movable arm engages the bumper on a corner of the bumper to provide the bumper with an effectively progressive spring rate.
