Abstract
A protection unit, including a power switching device, with a mechanical switch. To improve the multipurpose nature of the power switching while making lockout easier and more reliable, provision is made for the power switching device to include an electrical actuator actuating the mechanical switch and being controlled by an electronic control unit, which is itself powered via an auxiliary switching device. A lockout system with a lock is provided, which, in a lockout configuration, mechanically keeps the mechanical switch and the auxiliary switching device in an isolation configuration, and, in operating configuration, allows the mechanical switch and the auxiliary switching device to move between the conduction configuration and the isolation configuration.
