Abstract
A circuit protection device is provided between a direct-current power supply and a protection object circuit connected to the direct-current power supply, and protects the protection object circuit from an overvoltage of the direct-current power supply by shutting off a connection between the direct-current power supply and the protection object circuit using a predetermined interrupting element. The circuit protection device includes a bypass circuit which suppresses an electric alternating-current component from flowing to the interrupting element.
