摘要： A direct current electrical switching apparatus includes a first contact in electrical communication with first and third arc runners, a second contact in electrical communication with second and fourth arc runners, a movable contact, a first arc chamber including first arc plates having a first width, a second arc chamber including second arc plates having a greater second width, an operating mechanism, and a magnet assembly cooperating with the arc chambers to establish generally oppositely directed magnetic fields. The magnetic fields cause one of a first arc and a second arc to enter one of the arc chambers depending upon a direction of current flow between the contacts. The electrical switching apparatus is rated for a first magnitude of current flowing from the first contact to the second contact and for a greater second magnitude of opposite second current flowing from the second contact to the first contact.

摘要： An embedded system includes a first wireless node and a number of second wireless nodes, each of which includes a wireless transceiver, a memory storing a schedule defining transmission and reception of test packets, and a processor transmitting and receiving the test packets responsive to the schedule. The memories store a corresponding predetermined application employing some of the wireless communications, and a corresponding predetermined measurement function measuring wireless communication performance. A corresponding one of the schedules is executed by the corresponding predetermined measurement function. The second wireless nodes wait to receive a number of the test packets before being synchronized with their schedule and receiving and transmitting the test packets according to their schedule. The processors store data from the test packets to assess wireless communication performance between corresponding nodes.

摘要： A subframe is coaxially pivotally mounted with a movable frame of the operating mechanism of a molded case circuit breaker and is locked to the frame by a bell crank pawl which is pivotally mounted on the subframe. A leaf spring assembly rigidly attached to the subframe overlies the movable contact finger to engage the same in the circuit ON condition of the circuit breaker to provide desired contact force. The bell crank pawl is released upon an incrementally small amount of initial movement of the movable contact arm in response to blow-open magnetic repulsion forces to release the movable contact finger for pivotal opening movement relative to the movable frame of the circuit breaker operating mechanism.

摘要： Molded insulating shell halves are secured together around a blowout coil, stationary and movable contacts to pivotally trap an armature assembly therebetween. Windows are provided in the shell halves to ventilate the electromagnet coil during operation. The electromagnet is removable through the window without disassembly of the contactor. Contact and armature adjustment is accomplished through additional window openings. An arc chute having left and right-hand arc extinguishing chambers each sub-divided into upper and front chambers splits the arc into four series segments and increases the overall length of the arc significantly over similar prior art devices.

摘要： A linear acting ball latch is released by a rotary latch release member in the form of a rotor for a high torque, short stroke rotary electric motor which is electrically energized through a capacitor discharge system to release the latched member for spring biased movement into engagement with a bridging contact, thereby forcing the contact open from stationary contacts. A clapper type armature drives the contacts between open and closed positions through tubes, one of which extends through the latch mechanism. The tubes have spring biased plungers connected with the movable contact member to provide a low gradient spring force to the contacts permitting separation by the latch tube assembly and providing contact pressure when the magnetic operator closes the contacts. A manually operable handle and reset cam are disposed over the rotary latch mechanism and have mechanical connection with the latch release rotor to provide for manual operation of the release and for manual resetting of the latch mechanism. The wearable parts and time dated parts are all housed in a powerhead module which is readily detached from a base module and electronics module.

摘要： An arc extinguishing structure for a circuit breaker (2) wherein an arc chute is provided with a pair of transverse barrier plates (38) spaced apart to provide a centrally located opening (40) and spaced away from an upstanding wall (4a) of the breaker housing (4) so as to direct ionized gases associated with an electric arc drawn between separating contacts (8,20) through the arc plates (36) and central opening (40) against the upstanding wall (4a) thereby to be redirected along the wall (4a) and exhausted to the atmosphere through unrestricted openings (6a,4b) provided at opposite upper and lower ends of the wall. The barriers (38) project into the areas of the passageways (6a,4b) to prevent direct access to the switch contacts (8,20) through the passageways and to increase the length of the exhaust path for the arc gases.

摘要： A plurality of coil springs (6) are secured to the flat inner surfaces (4a) of a jaw type connector (12) to receive a flat conductor (20, 24) such as a bus bar between the opposed springs, the individual coils of each spring (6) engaging the surfaces of the connector (4) and bus bar (20, 24) to provide a compliant, multiple path electrical connection between the connector and bus bar. The springs are plated with a material having a low interface resistance (Rp) with respect to the resistance of the spring wire (Rw) to minimize the net change in resistance of any individual current path in the event of contact interface breakdown between a spring coil and bus bar or connector, thereby reducing or eliminating harmful damage to the spring.
