Duct heater assembly, 50TJM 18 480 V
Heater capacity(kW) is based on heater voltage of 380v or 480v. If power distribution voltage to unit varies from heater voltage, heater kW will vary
accordindly. To Detemine heater capacity at actual unit voltage, muptiply 480v capacity by multipliers found in table " Multiplication Factors" above.
Duct heater assembly, 50TJM 28 - 34 480 V
EXAMPLE: 30 kW (at 480 v) heater o
= 30.0 (0.7 multiplication factor)
= 21kW
