Abstract
A number of surge protection device disconnector designs provide protection to a load over a full range of fault currents provide adequate surge protection as well. The designs quench arcs that may tend to occur as a result of MOV faults, thereby protecting the surrounding components.
Claims78
A surge protection device for protecting a load connected to at least one voltage source from a power source, comprising:
- an overcurrent fuse electrically connected to said at least one voltage source;
- a thermal fuse spring electrically connected to said overcurrent fuse;
