19. Commutating Capacitors
Commutating in layman terms
Is a reduction in severity of a punishment by law.
Commutating in electrical terms
A reversal of current direction or the conversion of alternating current to unidirectional current
The cap takes the heat off the SCR

20. Type SCR and SNU Comparison
* This rating only, all the rest are 60 A

21. Type SCR and SNU
Threaded studs on the SCR give the higher current rating
The SNU aluminum case is ideal for welding applications where current flowing thru the capacitor creates a magnetic field that heats ferrous materials
