Contact factory for 380-3-60 data.
2.
For Split System Evaporators with SCR reheat, use the values above.
The values above were calculated per UL Standard 1995.
FLA = Full Load Amps (Input Amps); WSA = Wire Size Amps (Minimum Supply Circuit Ampacity); OPD = Maximum Overcurrent Protective Device Size
RLA = Rated Load Amps; LRA = Locked Rotor Amps
* R = In the Row; M = In the Row with Econ-O-Coil
