Notes:
1. The current value of combination unit is the total value of each basic
model(refer to Table.8-3)
For example: 46HP=14HP+16HP*2
Power current: MCA=27.9+33.4*2=94.7
TOCA=31.8+32.8*2=97.4
MFA=35+35*2=105
Compressor: RLA=(17.4+10.5)*3
OFM:
FLA=5.9+5.9*2=17.7
2. RLA is based on the following conditions.
Indoor temp. 27°C DB/19°C WB;Outdoor temp. 35°C DB
3. TOCA means the total value of each OC set.
4. MSC means the Max. current during the starting of compressor.
5. Voltage range
Units are suitable for use on electrical systems where voltage supplied to
unit terminals is not below or above listed range limits.
6. Maximum allowable voltage variation between phase is 2%.
7. Selection wire size based on the larger value of MCA or TOCA.
8. MFA is used to select the circuit breaker and the ground fault circuit
interrupter (earth circuit breaker).
Remark:
MCA: Min. Current Amps. (A)
TOCA: Total Over-current Amps. (A)
MFA: Max. Fuse Amps. (A)
MSC: Max. Starting Amps. (A)
RLA: Rated Locked Amps. (A)
OFM: Outdoor Fan Motor.
FLA: Full Load Amps. (A)
KW: Rated Motor Output (kW)
