A heater system for a non-combustible aerosol-generating device includes a heater element and a fuse element. The heater element has a heating region, a first terminal and a second terminal. The fuse element is electrically connected between the first terminal and the second terminal in parallel with the heater element. The fuse element has a region configured to induce a localized hot spot to cause the fuse element to open circuit in response to power applied between the first terminal and the second terminal.
