Notes:
1. Coils available with 24-volt magnetic or mercury contactors, load carrying P.E switches, and P.E. switch with magnetic or mercury contactors.
2. Available kW increments are by 0.5 kW from 1.0 to 8.0 kW, by 1.0 kW from 9.0 to 18.0 kW, and by 2.0 kW from 18.0 to 46.0 kW.
3. Each stage will be equal in kW output.
4. All heaters contain an auto-thermal cutout and a manual-reset cutout.
5. The current amp draw for the heater elements is calculated by the formula at the end of this section.
6. The maximum allowable kW is based on the largest kW possible per a voltage and the minimum airflow per an inlet size and kW.
7. SCR not available with 575V.
(a) No 5.5 kW available.
(b) No 6.5 kW available.
