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. 本发明公开了危险场所合规固态电路保护装置，该危险场所合规固态电路保护装置包括安全闭锁部件，该安全闭锁部件确保断路，作为负责人员完成电力系统维护保养任务的保障。该安全闭锁部件可包括与物理锁元件接合的机械闭锁部件、通过固态断路器装置的控件实现的电气闭锁部件以及它们的组合。可向负责人员提供以下视觉装置反馈和确认：已成功激活该闭锁部件，以及已成功去激活该闭锁部件以重新连接并恢复负载侧电路的操作。
