1. Units drawing less than 100 amps are available with or without door interlocking disconnect.
Units drawing more than 100 amps are not available with door interlocking disconnect.
2. Units drawing less than 48 amps are available with or without line fusing.
Units drawing greater than 48 amps have line fusing as standard.
3. Units with electric heat must not be run below the minimum cfm listed above.

Useful Formulas:
Single Phase Heater Amps = (kW x 1000)/ Voltage
Three Phase Heater Amps = (kW x 1000)/ (Voltage x 1.73)
Minimum Circuit Ampacity = MCA
MCA = 1.25 x (heater amps + motor FLA)
Maximum Fuse Size or Maximum Overcurrent Protection = MFS
MFS = (2.25 x motor FLA) + heater amps
kW = (Air Flow x Delta T) / K
Delta T = (kW x K) / Air Flow
K = 3145 (English)
K = 824.7 (SI)
HACR (Heating, Air-Conditioning and
Refrigeration) type circuit breakers are
required in the branch circuit wiring for all
fan-coils with electric heat.
SeeTables ED- 3 through ED-6 for motor
FLA’s
Select a standard fuse size or HACR type
circuit breaker equal to the MCA.
Use the next larger standard size if the
MCA does not equal a standard size.
Standard fuse sizes are:
15, 20, 25, 30, 35, 40, 45, 50, 60 amps
