Fig. 6 shows a picture of three sizes of units that will be discussed in 

 this section together with the range of currents that these units can con- 

 duct. The actual current rating will depend upon the ability of the de- 

 vice to dispose of the heat dissipated in the unit. A description of how 

 the rating is reached is given in Section 6.
