摘要： An interrupter system includes a first coil and an interrupter electrically connected to the first coil. The interrupter includes: a first terminal; a second terminal electrically connected to the first terminal; a third terminal electrically separated from the first terminal and the second terminal; a heat generating element electrically connected to the third terminal; and an explosive configured to be ignited by the heat generating element to produce a gas for interrupting an electrical connection between the first terminal and the second terminal. The first coil is electrically connected to the heat generating element via the third terminal. Moreover, the first coil is configured to, when an abnormal current flows between the first terminal and the second terminal, generate an electric power for igniting the explosive from the abnormal current.

摘要： An electric circuit device and method is for recognizing a closed switch contact as well as a protective ground conductor interruption in a one- or multiphase electric supply line. A control of a residual current monitoring device (RCMB control) includes one fault current control unit for generating a control signal pattern including a series of switching-on impulses forwarded to a first electronic switch unit to activate a possible artificial passive fault current on one or more active conductors and the protective ground conductor (as a return conductor), this fault current actually flowing, being recognized, and evaluated in a closed circuit in a closed switch contact to be tested and an intact protective conductor. Owing to control signal patterns varying during monitoring, a reliable detection of the artificial passive fault current is ensured even in large dynamic disturbance levels while the electric installation (supply line) to be monitored is in operation.

摘要： An apparatus comprises an Ethernet port including high-side transformers and low-side transformers. High-side current paths supply high-side currents form a high voltage rail to high-side center taps of the high-side transformers. Low-side current paths supply or do not supply low-side currents from a low voltage rail to low-side center taps of the low-side transformers, and convert the low-side currents to sense voltages. A controller configures the low-side current paths to either supply or not supply the low-side currents to the low-side center taps when none of the sense voltages exceed a voltage threshold representative of an overcurrent threshold or when at least one of the sense voltages exceeds the voltage threshold, respectively. A current monitor injects additional current into the low-side current paths only when at least one of the high-side currents exceeds the overcurrent threshold.

摘要： The line power and neutral conductors for an arc fault sensing circuit interrupter such as in a miniature circuit breaker are arranged as a rigid conductor surrounding and holding an insulated flexible conductor when passing through the Ground Fault Interrupter current transformer. Voltage metering takes place across the rigid conductor to enable arc fault detection and ground fault detection in the miniature circuit breaker within the space of a single current transformer.

摘要： A ground fault circuit interrupter (GFCI) for opening a circuit when a ground fault has been detected in an attached circuit includes a current path structure containing no more than one splice and no more than one pair of contacts. A cantilevered movable contact arm and an activation device that moves in a linear fashion can be provided to open the current path structure when a ground fault is detected by the GFCI. In addition, the GFCI can include a transformer boat and solenoid bobbin that are snap fit onto a circuit board and located adjacent each other to provide rigidity to the circuit board and GFCI. The GFCI can be tested by a test switch that includes an integral cantilevered extension from an electrical terminal disposed over a resistor such that the cantilevered extension can be bent by a test button to contact a lead of the resistor and simulate a ground fault condition for the GFCI. Furthermore, the GFCI can include a housing with an outer portion that defines a uniform width channel adjacent a wire contact point to allow quick and easy connection to ground wires.

摘要： A microprocessor-based circuit breaker includes a removable chip that defines the current rating or ground fault current for the breaker. The breaker includes mechanical components that trip to disconnect the load terminal from the line input. The mechanical components include a floating breaker arm, trigger and tripper lever that cooperate to control the tripping of the breaker. A spring between the breaker arm and trigger, together with cam surfaces defined in the breaker switch cooperate to form a floating linkage to control the position of the breaker arm during on/off activation and current fault conditions. The circuit breaker also includes multiple indicia to provide a visual indication of the type of fault condition sensed by the breaker.

摘要： In a the method for adjusting thermal overload cutouts, after a synchronization of bimetallic strips and optionally a preadjustment of a cutout mechanism, the bimetallic strips are acted upon by current for a specific time, at the end of which the actual adjustment procedure takes place. In this, a residual cutout distance still remaining between the bimetallic strips and a mechanical shutoff point is reduced by zero by an apparatus. This adjustment method eliminates repeat testing with time-consuming cooldowns.

摘要： A multi-pole circuit breaker assembly for interrupting AC power to a load upon the detection of an earth leakage fault or an overcurrent condition includes a pair of circuit breaker units mounted adjacent to an earth leakage module. The earth leakage module includes an electronic circuit that senses a current imbalance between the power line lead and the neutral line lead using a differential transformer. In response to a current imbalance greater than a predetermined value, the electronic circuit periodically energizes a switching circuit that provides power across a solenoid. The solenoid, when actuated, engages a common trip mechanism to open concurrently the contacts of the circuit breakers units. The common trip mechanism includes an elongated bar that extends through the casing of the earth leakage module and the circuit breaker units. The elongated bar engages a U-shaped trip member pivotally disposed in each circuit breaker. Each trip member has a depending member extending from a leg that trips its respective circuit breaker unit when pivoted upwardly by the solenoid.

摘要： An accelerating mechanism in an overcurrent relay for accelerating the speed of moving operation of a resetting bar or the speed of motion in a normally closed contact caused by the resetting bar. In the application of the relay to any resetting mechanism, which effects resetting with a movement of the resetting bar, the relay can eliminate a very hazardous abnormal operation that a resetting operation is stored in a toggle mechanism, thus improving the safety of the resetting mechanism.

摘要： A multiple-pole ground fault interrupter, enclosed in an insulated housing, formed with multiple compartments, includes ground fault detection circuitry for detecting ground fault current that can be a personnel hazard. The ground fault interrupter includes a single trip solenoid assembly having multiple windings, each winding corresponding to one of the poles. The trip solenoid is mounted on a printed circuit board and electrically connected to the ground fault detection circuitry disposed thereon. The printed circuit board together with the trip solenoid assembly is disposed in a single compartment which reduces the amount of interconnection wiring between compartments, which, in turn, results in a reduced cost to manufacture the device. The use of a single trip solenoid assembly also results in the use of less components which further reduces the cost of manufacturing the device.
