Abbreviations:
MCA: Minimum Circuit Amps; TOCA: Total Over-current Amps; MFA: Maximum Fuse Amps; MSC: Maximum Starting Current (A); RLA:
Rated Load Amps; FLA: Full Load Amps
Notes:
1. Units are suitable for use on electrical systems where voltage supplied to unit terminals is not below or above listed range limits. Maximum
allowable voltage variation between phases is 2%.
2. Select wire size based on the value of MCA.
TOCA indicates the total overcurrent amps value of each OC set.
MFA is used to select overcurrent circuit breakers and residual-current circuit breakers.
MSC indicates the maximum current on compressor start-up in amps.
RLA is based on the following conditions: indoor temperature 27°C DB, 19°C WB; outdoor temperature 35°C DB.
