Motor Protective Circuit Breakers MPW - Technical Data
Altitude - Correction Factor
The MPW motor protective circuit breakers do not undergo
any change to their specified performance when applied at
an altitude of up to 2,000 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 2,000 meters, as shown in the
following table.
