General characteristics

(*) D350: 10 seconds (**) Steady state (***) Total harmonic distortion between phases, no-load or on-load (non-distorting)

Ratings 50 Hz – 1500 R.P.M.

kVA / kW – P.F. = 0.8

(*) 12-wire option
Ratings 60 Hz – 1800 R.P.M.

Efficiencies 400 V – 50 Hz (— P.F.: 0.8) (…… P.F.: 1)

Reactances (%). Time constants (ms) – Class H / 400 V 

Transient voltage variation 400 V – 50 Hz – For a starting P.F. other than 0.6, the starting kVA must be multiplied by K = Sine P.F. / 0.8
– For voltages other than 400V (Y), 230V (Δ) at 50 Hz, then kVA must be multiplied by (400/U) 2 or (230/U) 2

Efficiencies 480 V – 60 Hz (— P.F.: 0.8) (…… P.F.: 1) 

Reactances (%). Time constants (ms) – Class H / 480 V 

Transient voltage variation 480 V – 60 Hz

– For a starting P.F. other than 0.6, the starting kVA must be multiplied by K = Sine P.F. / 0.8
– For voltages other than 480V (Y), 277V (Δ), 240V (YY) at 60 Hz, then kVA must be multiplied by (480/U) 2 or (277/U) 2 or (240/U) 2.
– Transient performance of the PMG option, consult us.
3-phase short-circuit curves at no load and rated speed (star connection Y)

Influence due to connection
For (Δ) connection, use the following multiplication factor:
– Current value x 1.732.
3-phase short-circuit curves at no load and rated speed (star connection Y)

Influence due to short-circuit Curves are based on a three-phase short-circuit.
For other types of short-circuit, use the following multiplication factors.
