42BHC,BVC ELECTRIC HEATER DATA
LEGEND
NOTES:
1. Stages available:
Single phase: 1-12 kW, 1 stage only
3-12 kW, 1 stage or 2 stage
Three phase: 1-40 kW, 1 stage only
4-40 kW, 1 or 2 stage
12-40 kW, 1, 2 or 3 stage
2. Electric Heating Capacities (Btuh) = Heater kW x 3413
3. Electric Heater Amperage for Single-phase Power
= (Heater kW x 1000)/Applied Voltage Electric Heater Amp. for 3-phase Power
= (Heater kW x 1000)/(Applied Voltage x 1.73).
MOTOR PERFORMANCE DATA (AMPS)
NOTES:
1. Motor Full Load Amps refer to National Electric Code (NEC)
Amps; actual motor nameplate amps may vary.
2. NEC data extrapolated for 277 v.
3. Motors are open drip proof, ball bearing, single speed, 1750 rpm
rated at continuous duty, 140 F ambient with reversible rotation.
Service Switches:
The service switch is an On/Off switch on incoming power
supply to unit. Proper amperage load must be determined
before switch can be selected. The range of the fused or
non-fused service switch is 0 to 40 amps.
Amp Load = [Motor amps + Heater amps (if required)]*
1.20.
The UL listing signifies that Carrier’s fan coil units have been examined
by UL and comply with the organization’s applicable standards of U.S.
and Canadian national product safety standard, UL 1995/CSA C22.2
No. 236.
