Fused electrical protection assemblies and surge protective devices

A surge protective device comprising:

• a voltage-switching/limiting component;
• a spark gap assembly, the spark gap assembly including a first spark gap electrode and a second spark gap electrode defining a spark gap therebetween;
• and
• a thermal disconnector mechanism positioned in a ready configuration, wherein the voltage-switching/limiting component is electrically connected in electrical series with the spark gap, the thermal disconnector mechanism being repositionable to electrically disconnect the voltage-switching/limiting component from the spark gap, the thermal disconnector mechanism including:
• the first spark gap electrode;
• a voltage-switching/limiting component electrode electrically connecting the spark gap to the voltage-switching/limiting component;
• and
• a solder securing the first spark gap electrode in electrical connection with the voltage-switching/limiting component electrode in the ready configuration;
• wherein:
• the solder is meltable in response to overheating in the surge protective device;
• and
• the thermal disconnector mechanism is configured to displace the first spark gap electrode away from the voltage-switching/limiting component electrode and thereby electrically disconnect the voltage-switching/limiting component from the spark gap when the solder is melted.
