STATIC TRANSFER SWITCH ASSEMBLY Part Numbering System
Model Number always starts with STS: STS (A) –(B) –(C) –(D) –(E) –(F) -R (G)(G)
(A) = Cage Size: 1=19" ; 2=23"
(B) = Phases: 1=Single Phase ; 2=Bi-Phase (180 degrees) ; 3=3-Phase (120 degrees) ; 4=2 out of 3 phase (120 degrees)
(C) = Power: 1=10KW ; 2=20KW
(D) = AC Voltage: 0=100VAC ; 1=120VAC ; 2=277VAC
(E) = AC Frequency: 5=50Hz ; 6=60Hz ; 4=400Hz
(F) = Designates current revision level
(G) = Option Code: 00=no option is required ; or Refer to the STS controller option chart
Example:
