Notes:
1. As standard, 140-250 ton (60 Hz) units and 140-200 ton (50Hz) units have a single point power connection. Optional dual point power connections are
available. As standard, 275-500 ton (60Hz) units and 250-400 ton (50Hz) units have dual point power connections. Optional single point power con-
nections are available on 380V, 460V 575V/50 Hz and 400V/50 Hz units.
2. Max Fuse or HACR type breaker = 225 percent of the largest compressor RLA plus 100 percent of the second compressor RLA, plus the sum of the
condenser fan FLA per NEC 440-22. (Use FLA per circuit, NOT FLA for the entire unit).
3. MCA - Minimum Circuit Ampacity - 125 percent of largest compressor RLA plus 100 percent of the second compressor RLA plus the sum of the
condenser fans FLAs per NEC 440-33.
4. RECOMMENDED TIME DELAY OR DUAL ELEMENT (RDE) FUSE SIZE: 150 percent of the largest compressor RLA plus 100 percent of the second
compressor RLA and the sum of the condenser fan FLAs.
5. RLA - Rated Load Amps - rated in accordance with UL Standard 1995.
6. Local codes may take precedence.
7. Control VA includes operational controls only. Does not include evaporator heaters.
8. XLRA - Locked Rotor Amps - based on full winding (x-line) start units. YLRA for wye-delta starters is ~1/3 of LRA of x-line units.
Voltage Utilization Range:
Rated Voltage 200/60/3 230/60/3 380/60/3 460/60/3 575/60/3 400/50/3
Use Range 180-220 208-254 342-418 414-506 516-633 360-440
9. A separate 115/60/1, 20 amp or 220/50/1, 15 amp customer provided power connection is required to power the evaporator heaters (1640 watts).
10. If factory circuit breakers are supplied with the chiller, then these values represent Maximum Overcurrent Protection (MOP).
