Notes:
1. Voltage Utilization Range: +/- 10% of rated voltage. Rated voltage (use range): 400/50/3 (360-440)
2. MCA–minimum circuit ampacity
3. MOP–maximum overcurrent protection
4. RLA–rated load amps are rated in accordance with UL Standard 1995.
5. LRA–locked rotor amps are based on full winding starts.
6. LRA YD–Locked Rotor Amps in Wye configuration. LRA XL–Locked Rotor Amps in the Delta configuration.
7. Local codes may take precedence.
8. Data containing information on two circuits shown as follows: circuit 1/circuit 2.
9. Standard condensing temperature option refers to entering condenser water temperatures 95°F (35°C) or below.
