Manual Motor Protectors - MPW Technical Data
Technical Data
Altitude - Correction factor
The MPW manual motor protectors do not undergo any
change to their specified performance when applied at an
altitude of up to 2000 meters above sea level.
However, as the altitude increases, the atmospheric properties
vary in terms of dielectric rigidness and pressure.
Therefore, current and voltage correction factors must be
applied for altitudes exceeding 2000 meters, as shown in the
table on the right
Altitude
(above sea level) - h
h ≤ 2000 m 690 V 1 x I
2000 < h ≤ 3000 m 550 V 0,96 x I
3000 < h ≤ 4000 m 480 V 0,93 x I
4000 < h ≤ 5000 m 420 V 0,90 x I

DC operation
The MPW16, MPW25 and MPW65 motor protective circuit
breakers can also be used for operating continuous current
loads. For such operation it is necessary to connect 2 or 3
poles in series.
See recommended circuits and their voltage limits in the
table on the right.
