Abstract:
A circuit protection device comprising:at least one set of reed members having a pair of reed members, wherein each of the reed members is constituted by a magnetic material and disposed in such a way as to be opposed to the other of said reed members and has an end disposed in such a manner as to be apart by a predetermined gap from and contactable with an end of the other of said reed members; a magnetic-field generating unit placed in vicinity of the reed members set and adapted to generate a holding magnetic field for maintaining a state, in which the end of said reed members are in contact with each other, after the ends of said reed members are attracted to each other, and said ends are closed; and a contact gap reduction unit for reducing the gap to a gap corresponding to a pull-in of the magnetic field generated by said magnetic-field generating unit, the contact gap reduction unit contacting one of the reed members.
