The auxiliary contacts are used for signaling functions and electrical interlocking, providing an increase of the numbers of contacts used.
If necessary, a number of auxiliary contacts are provided and they are fixed on the mobile part of the magnetic conductor of the LC1-D contactor. They come in versions with 2 or 4 auxiliary contacts in different combinations of NC and NO.
– increase the number of contacts used up to four, in different combinations.
– connecting simultaneously with the rest of the contact system of the contactor.

LA2-DN determines the time range from 0.1 up to 180s in the command scheme.
They are frequently used in combination with LC1-D series contactors, for starting system “star-delta” type, used to command the electric motor, assuring the necessary time for motor starting.
If necessary, the auxiliary contacts are mounted on the contactors tors from LA8-DN11 series. They come with 2 auxiliary contacts (NO and NC).
