A protection apparatus is provided that can use a thermal fuse at higher voltage and higher current. The protection apparatus includes a protection circuit connected in series between a power supply and a load. The protection circuit includes a thermal fuse with a predetermined operating temperature, activated in response to sensing overheating of the power supply and/or load, and an electrosensitive fuse connected in parallel with the thermal fuse, and activated at a predetermined operating current. The electrosensitive fuse is adapted to be activated only after the thermal fuse has been activated at the predetermined operating temperature.
