2.3 3 PHASE INPUT POWER REQUIREMENTS
The BL10000 series power supplies within the model number range C2 to C6 are designed to be used with a
four wire “ Wye” input configuration. Units that are to be supplied with “Delta” inputs above 277 volts require the
use of “back-up” fuses to provide supplemental protection. This is due to the interrupt rating of the circuit
breaker used. The chart below indicates the proper fuse based on the model number of the power supply. This
chart can also serve as a guide for sizing the input service to the unit.
The following lists should be used to select the proper line fuse size for the model numbers shown. The
selections are based on nominal line voltages and maximum output power. All fuses carry a 600 VAC minimum
voltage rating.
