Abstract

An overcurrent protection device for a circuit to be monitored, includes at least one trigger unit, which is configured for an interruption of the circuit in at least one trigger situation and which comprises at least one conductor section, which is configured for a conduction of a current to be monitored, at least one trigger element, which comprises at least one magnetically and thermally shape-shiftable material and is, in the trigger situation, configured for a thermally-induced and/or magnetically-induced deformation in dependence on a current that flows through the conductor section, and at least one actuation element, which is operatively connected with the trigger element and is configured for a transmission of at least one actuation movement and/or at least one actuation force to at least one interrupter switch.
