Specifications table for the specific device.The operating values  
of a MOV need to be deratedat high temperatures as shown in  
Figure 1. Because varistors only dissipate a relatively small  
amount of average power they are not suitable 0for repetitive  
applications that involve substantial amounts of average power  
dissipation.
