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： 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.
