4.1 Power ratings
4.1.1 Vacon NXP/C – Mains voltage 380—500 V
High overload = Max current I
S
, 2 sec/20 sec, Rated overload current, 1 min/10 min
Following continuous operation at rated output current, rated overload current
for 1 min, followed by a period of load current less than rated current, and of
such duration that the r.m.s output current, over the duty cycle, does not exceed
rated output current (IH)
Low overload = Max current I
S
, 2 sec/20 sec, Rated overload current, 1 min/10 min
Following continuous operation at rated output current, rated overload current
for 1 min, followed by a period of load current less than rated current, and of
such duration that the r.m.s output current, over the duty cycle, does not exceed
rated output current (IL)

Table 4-1. Power ratings and dimensions of Vacon NX 6- and 12-pulse drives supply voltage 380—500V.
Note: The rated currents in given ambient temperatures are achieved only when the switching fre-
quency is equal to or less than the factory default (automatic thermal management).
*The dimensions indicated are for the basic 6-pulse IP21 version of the converter cabinet. Some op-
tions may increase the width, height or weight of the cabinet. See the delivery-specific documenta-
tion for more details.
