Catalog Number

For use with:

Fault differentiation: with manual reset (thermal overload) with auto reset Thermal overload pre-alarm

Provides indication between an overload trip and a short circuit trip.

Advanced control unitsonly

LUFDA10

Signals when the motor current reaches 1.05 of the full load setting on the control unit. Provides a signal proportional to the average currents in the three phases divided by the full load current setting of the control unit. The output corresponds to a load status of 0–2 times the full load setting of the control unit. Provides a convenient way to reduce control wiring and allow for connecting starters to a communications network by providing 24 Vdc for the starters.

[8] The control unit contains solid-state overload relay and control power source for TeSys Ultra. For more details on the different control units, their functions, and placement on the power base see Control Units and Functions, page 17-27. [9] Control units for 4.5–18 and 8–32 can be used only with 32 A rated power bases (LUB32, LUB320, and LU2B32). [10] Complete the catalog number by adding the appropriate code from (for example LUCAX6FU). [11] DC voltage with range of 0.90 to 1.10 of nominal. [12] Voltage code to use for a power base with a communication module.

[13] See page 17-27 for placement on the power base. [14] Increases the breaking capacity of the motor starter. [15] Offers customization for specific application requirements.
