[2] Holding circuit contacts are not provided as standard; refer to Table 16.242 for kit. [3] Replace the three bullets (●●●) in the catalog number with the coil voltage code. Refer to the standard voltage codes listed in Table 16.241. [4] Type DPS 4-pole starter not available. Suggest 3-pole device with auxiliary contact. [5] Does not include holding circuit interlock—order auxiliary contact. [6] Use for 30 to 40 A starters. For 50 A starters, use the 9999BLX bracket. [7] Append the coil voltage code from Table 16.241.
