A non-mechanical-interfacing electronic switch or a mechanical-interfacing electronic switch are controlled to modulate between an active state and an inactive state based on electronic action. The switch includes an aperture defining an opening in a housing, and the opening defines an insertion path. A transmitter transmits a signal to a receiver along a signal path. To control the non-mechanical-interfacing electronic switch, a mechanical lockout device having a protrusion is inserted through the opening of the aperture along the insertion path. To control the mechanical-interfacing electronic switch, a mechanical control part have a protrusion is moveable to interrupt the signal. Methods of locking the non-mechanical-interfacing electronic switch with the mechanical lockout device as well as methods of locking the mechanical control part of the mechanical interfacing electronic switch with the mechanical lockout device are also provided.

Mechanical lockout for solid-state switch

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.

Hazardous location compliant circuit protection devices having enhanced safety intelligence, systems and methods

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.

Hazardous location compliant circuit protection devices, systems and methods with safety lockout/tagout components

Modular circuit protection devices and configurable panelboard systems include arc-free operation, thermal management features providing safe operation in hazardous environments at lower cost and without requiring conventional explosion-proof enclosures and without entailing series connected separately provided packages such as circuit breaker devices and starter motor contactors and controls.

Configurable modular hazardous location compliant circuit protection devices, systems and methods

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.

Configurable modular hazardous location compliant ciruit protection devices, systems and methods

Aspects and techniques of the present disclosure relate to enclosures, such as, electrical enclosures, for example, explosion-proof enclosures, and including advantageous features and methods usable with such enclosures. Disclosed features and techniques relate to: an enclosure fastening device; a visual indicator; an enclosure handling assist arrangement; a control handle; and a reset controller.

Enclosure arrangements; components; and methods

A cable gland assembly includes a gland nut defining a longitudinal axis. The gland nut includes an interior wall defining a gland nut opening and the interior wall includes a stop. A bushing is disposed within the gland nut opening proximate the stop. The bushing defines a bushing opening configured to receive a cable therein. A sleeve is moveably disposed within the gland nut opening adjacent the bushing. The cable gland assembly also includes a body defining a body opening configured to receive at least a portion of the cable therein. The body is configured to couple to the gland nut, and upon tightening of the gland nut to the body, the gland nut moves along the longitudinal axis compressing the bushing between the gland nut and the sleeve and around the cable. When the sleeve engages with the stop, further compression of the bushing is restricted.

Mechanical lockout for non-mechanical-interfacing electronic switch

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 a hazardous location.

Compliant, hazardous environment circuit protection devices, systems and methods

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.

An operator for an electrical switching apparatus includes an actuator configured to be grasped by a user. A linkage is attached to the actuator at a first end of the linkage and configured for extending through an enclosure housing the electrical switching apparatus. An engagement assembly is attached to the linkage at a second end of the linkage such that when the operator is mounted to the enclosure movement of the actuator outside of the enclosure causes movement of the engagement assembly inside the enclosure. The engagement assembly includes an extension arm attached to the linkage and an attachment member attached to the extension arm. The attachment member is configured to engage a toggle of the electrical switching apparatus in the enclosure to move the toggle between at least two positions.
