1. (0,1) - 0 = no service disconnect OR 1 = with service disconnect.
2. (1,2) - 1 = with service disconnect, no breaker jumper bar OR 2 = with service disconnect & breaker
jumper bar.
3. 6HK3 = 3-Phase with terminal block connectors only, 6HK4 = 3-Phase with service disconnect.
Table 5. KW & MBH Conversions - For Total Power Input Requirement
For a power distribution voltage that is different than the provided nominal voltage, multiply the kW and MBH
data from the table by the conversion factor in the following table.
DISTRIBUTION POWER NOMINAL VOLTAGE CONVERSION FACTOR
208V 240V 0.75
220V 240V 0.84
230V 240V 0.92
