How to Order

1.	Specify the Class Number and the Type Number.

2.	If all coils are at the line voltage, and not Sizes 6 or 7 (Sizes 6 and 7 are supplied with a fused transformer with 120 Vac as standard), select the voltage code from the table belowa:

 

Table 16.112:

Line	Control	Code
208 240 380 480 600	208 240 380 480 600	V08 V03 V05b V06 V07

a	This table is for 60 Hz; see below for codes for 50 Hz.

b	See below for sizing and pricing of 380 V starters.

3.	If the coils are at a different voltage than line supply, or Size 6 or 7, select a voltage code from the table belowc and also select a Form code from the table to the right (note that a Form code may be used with any voltage code, except as noted):

380 Vac, 50 Hz Starters

The Class 8600 starters are available for 380 Vac, 50 Hz applications. See table below for maximum horsepower ratings. To determine Type Number, select second digit based on NEMA Size as listed below. Select fifth digit based on horsepower requirement. Specify V05 voltage code. List prices for the same NEMA Size starter apply.
