%P

%P = % of nominal power.

The nominal power (Pn) is calculated by the LTMT main unit from the system settings: Pn = VT primary * Full load current.

In case of two-speed motor starters, the nominal power is:

  • Pn1 = VT primary * Full load current, when the motor runs in speed 1 or low speed

  • Pn2 = VT primary * Speed 2 Full load current, when the motor runs in speed 2 or high speed
