All the contactors of the N series can be
fitted with the mechanically latched control device tipe <<TA>>. By
this device the contactors, when operated, remains mechanically latched and the
closing electromagnet is automatically deenergized after a short delay which
ensures a correct latching; the opening operation is made by a proper release
electromagnet.
The <<TA>> device mounted on
the contactors of the sizes over 190 Amps, includes a low consumption auxiliary
contactor which controls the main closing electromagnet, thus allowing the
operation by simple push buttons or auxiliary contacts. The unit
<<TA>> is also complete with an antipumping device and with hand
operation levers; moreover, on request, it can be fitted with undervoltage
release.
The <<TAN>> contactors,
normally provided for D.C. supply, can also be fitted with a selfcontained
rectifier for A.C. supply. The elctrical charcteristics and the overall
dimensions of the <<TAN>> contactors are the same of the standard
type <<N>> contactors of the corresponding size and number of
poles with D.C. control and one more aux. contact beisides those actually
needed.
