42BHC ELECTRIC HEATER DATA AVAILABILITY 42BHC ELECTRIC HEATER DATA
LEGEND
NOTES:
1. Stages available:
Single phase:1-4 kW, 1 stage only
5-12 kW, 1 stage or 2 stage
Three phase:1-12 kW, 1 stage only
15-20 kW, 1 or 2 stage
25-40 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 Amperage for Three-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, 40° C (104° F) ambient with reversible
rotation.
Controls
Standard control features
• 4 in. x 4 in. junction box
Note that the motor leads are wired to the 4 in. x 4 in.
junction box which is mounted on the external panel.
Motor control options
• Interlocking disconnect switch*
• 24-v class 2 transformer (40 va)†
• 8-pole control terminal strip
• Motor power fusing*
• Motor control contactor**
Motor and electric heat control options
NOTE: Electric heat option requires same voltage as motor
and must include the control option. These control features
are standard with electric heat options and control option.
• Interlocking disconnect switch*
• Heater power fusing*
• 24-v class 2 transformer (40 va)†
• 8-pole control terminal strip
• Auto reset temperature limit switch
• Manual reset backup temperature limit switch
• Airflow safety switch
• 80/20 heater element wire
• Motor power fusing*
• Motor control contactor**
• Agency listed for 0-in. clearance
Electric heat options:
• Single-phase, single-stage or 2-stage heat
• Three-phase, single-stage, 2- or 3-stage heat
*Complies with NEC’s fused disconnect requirement.
†No control fusing necessary.
**Complies with NEC’s requirement for a motor starter with internal
heating elements when used with the factory’s standard motors with
integral thermal overload protection.
