Abstract: Disclosed is a control and protection device for a low-voltage electrical apparatus, comprising a pedestal and a control and protection module. The control and protection module may be plugged into the pedestal and is replaceable. The pedestal comprises a base and a housing, and is further provided with a moving contact, a static contact, and a current conductor connected to a main circuit current; a control electromagnet operation mechanism for controlling close and open of the moving contact and the static contact according to a control signal, and maintaining a close or open status of the moving contact and the static contact; a manual operation knob providing a control signal for controlling the close and open of the moving contact and the static contact; a control contact connected to the manual operation knob; and a current sensor for detecting a current that flows through the main circuit current conductor and generating a sensing signal.

Abstract: A method for configuring Internet Protocol Security (IPsec) protocol. The method includes configuring IPsec phase 1 Security Associations (SA) lifetimes and soft phase 2 SA lifetimes in a manner enabling efficient Dead Peer Detection recovery of secure communication between client and server in the event of a communication disruption and thereby preventing undesirable sustained periods of non-communication between client and server.
