  • Publication number: 20200211791
    Abstract: Solid state and hybrid circuit protection devices include improved chemical, static discharge and impact resistant housing construction, arc-free switching operation, secure terminal assemblies and thermal management features. The solid state and hybrid circuit protection devices are ignition protected and avoid possible explosions and therefore obviate a need for conventional explosion-proof enclosures to ensure safe operation of an electrical power system in a potentially explosive environment.

  • Publication number: 20200211792
    Abstract: Compliant electrical circuit protection devices are described for use in hazardous environments without presenting ignition risks for potentially explosive environmental conditions. Sensing features and systems may evaluate wiring limits and user selected settings for compatibility, detect loose connections and operating parameters to ensure safe operation of the device, and to intelligently diagnose and manage issues of concern for the circuit protection devices as well as the larger electrical power system.

  • Publication number: 20200211803
    Abstract: Hazardous location compliant solid state circuit protection devices include safety lockout components ensuring disconnection as a safeguard in the completion of power system maintenance and service tasks by responsible personnel. The safety lockout components may include a mechanical lockout interfacing with a physical lock element, an electrical lockout implemented through the controls of the solid state circuit breaker device, and combinations thereof. Visual device feedback and confirmation may be provided to personnel that the lockouts have been successfully activated, as well as successfully deactivated to reconnect and restore operation of the load side circuitry.

  • Publication number: 20190265745
    Abstract: An operator mechanism comprises a mechanical user interface and a contact assembly. The mechanical user interface is configured to be physically moved by a user. The contact assembly is coupled to the mechanical user interface such that movement of the mechanical user interface imparts movement to the contact assembly. The contact assembly includes a shaft having a longitudinal axis extending distally outward relative to the mechanical user interface to a distal end of the shaft. The contact assembly also includes a contact member coupled to and extending radially outward from the shaft. The contact member engages an actuator of a control device in the control enclosure when the contact assembly is moved. The contact member is selectively positionable longitudinally along the shaft and defines a shaft opening the shaft extends through such that the distal end of the shaft is distal of the shaft opening.

  • Patent number: 9553389
    Abstract: An electrical connector having an active cooling system is described herein. The electrical connector can include a conductor having an electrically conductive pin, and a conductor receiver slidably coupled to the conductor. The conductor receiver can include a wall having an electrically conductive material forming a cavity into which the pin is received. The conductor receiver can also include an insulating sleeve mechanically coupled to the wall. The conductor receiver can further include a heat sink mechanically coupled to the insulating sleeve and a channel that collects heat absorbed by the heat sink. The heat collected by the channel can be vented outside the conductor receiver. Alternatively, the wall of the conductor receiver can be coupled to an insulator and have at least one aperture that vents heat from the cavity to the insulator.

  • Patent number: 9093764
    Abstract: An electrical connector having a reduced temperature rise system is described herein. The electrical connector can include a conductor receiver and a conductor mechanically coupled to the conductor receiver. The conductor can include a pin having electrically conductive material and an exposed end. The conductor can also include at least one compression member disposed along a portion of the outer perimeter of the pin at a first distance from the exposed end. When the conductor is coupled to the conductor receiver, the compression member contacts the wall of the conductor receiver to the pin. Alternatively, the conductor receiver can have an electrically conductive first portion and a second portion. Further, the conductor can have a conductive pin and a guide pin. The guide pin can force the first portion to expand and compress around the conductive pin as the conductor is mechanically coupled to the conductor receiver.
