ABSTRACT:
A device and method for interrupting current flow to an electrically-powered apparatus is disclosed. The device includes a means for detecting a selected value of a physical parameter associated with the operation of the externally powered electrical apparatus, a trigger circuit incorporating an integrated circuit, a firing device which responds to the trigger circuit by generating a conductive plasma, an electronic measurement circuit to prevent unwanted firing of the firing device and thin conductors which are destroyed by the firing device when the conductive plasma forms an electric arc between them. Current flow to the electrically-powered apparatus is thereby terminated.
