The 1410-EON49 heater is a solid-state Bulletin 1410 motor winding heater from Allen-Bradley. It is designed as a solution to motor condensation problems. The Bulletin 140U heaters are available for motors rated from 15 to 600 Horsepower. Features of Bulletin 1410 products include a small size, cost-effectiveness, and a wide range of supported motor Horsepower ratings. The 1410-EON49 heater has a voltage rating of 600 Volts AC. When the 1410-EON49 heater is energized, an SCR controlled voltage causes current to flow in the motor windings. The heat that is produced is evenly distributed. The output voltage of the heater maintains a temperature that is 5 to 10 degrees Celsius above the ambient temperature rating and this protects it against condensation. The 1410-EON49 heater is connected in parallel with the 2 contacts of the motor starter. It automatically energizes when the starter contacts open (when the motor is powered off) and it automatically de-energizes when the starter contacts close (when the motor is powered on).
Approximately 1 to 3 Watts/Horsepower are supplied to the connected motors by the 1410-EON49 heater. The recommended storage and working temperature ranges for the 1410-EON49 heater are -25 to 85 degrees Celsius and 0 to 50 degrees Celsius, respectively. The output RMS current from the 1410-EON49 heater is approximately 15% of the full current load. The variations in the line voltage that range between +10% and -15% can cause a variation in the voltage applied by the 1410-EON49 heater to the motor windings by up to ±5%. The 1410-EON49 heater is approved for use by the UL 508 and CSA C22.2 No. 144 standards. The 1410-EON49 heater is also certified by CSA and UL standards.
