摘要： 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.

摘要： Solid state and hybrid circuit protection devices include improved arc-less switching capability and overcurrent protection, improved terminal assemblies and improved thermal management features that reduce or eliminate ignition sources for hazardous environments. 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 hazardous locations.

摘要： 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.

摘要： 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.

摘要： In one embodiment, a method includes, by a switch device, determining a position of an on/off input selector, the on/off input selector being located within a switch device, in response to determining the position of the on/off input selector is in an off position, operating one or more solid state switches to suspend current to one or more load-side terminals, determining whether the one or more load-side terminals of the switch device are electrically isolated, in response to determining the one or more load-side terminals of the switch device are electrically isolated, generating a prompt via a graphical user interface, and receiving, via the graphical user interface, one or more inputs, the one or more inputs including at least a request for safety lockout instructions.
