1) Available if ambient temperature is less than 30 °C (86 °F).
If ambient temperature is 40 °C (104 °F),
2) Special 4-pole high-efficiency NEMA motor.
3) 50% overload is allowed for one minute every five minutes if ambient temperature is less than 30 °C
(86 °F). 40% overload is allowed if ambient temperature is 40 °C (104 °F).
4) Available if ambient temperature is less than 30 °C (86 °F). If ambient temperature is 40 °C (104 °F),
