Contattori tripolari AF

To keep things moving, you need control

I contattori AF con tecnologia AF di serie definiscono un nuovo benchmark nel settore. La bobina a controllo elettronico offre numerosi vantaggi rispetto alle alternative convenzionali e, unitamente all'ampia offerta di prodotti ABB, crea configurazioni ottimali in qualsiasi situazione.

Vantaggi principali

  • Logistica ottimizzata e taglio dei costi di gestione grazie a poche varianti di prodotto
  • Supporto globale e impiego dello stesso prodotto in tutte le parti del mondo: la bobina da 100 - 250 V, c.a./c.c coprono tutte le tensioni di rete standard
  • La riduzione dell'80% del consumo elettrico della bobina consente un risparmio energetico
  • La tecnologia AF consente di superare cali e cadute di tensione

Caratteristiche principali

  • Fino a 560 kW - 400 V c.a.-3, 900 hp - 480 V e 2650 A - 690 V c.a.-1, 2700 A - per uso generale
  • Solo 4 bobine per coprire 24 V - 500 V c.a. e 20 V - 500 V c.c.
  • Connessione a vite, a molla e per capocorda a occhiello
  • Scaricatore di sovratensione integrato
  • Kit di connessione e unità di interblocco per un montaggio facile, rapido e sicuro di avviatori-invertitori e avviatori stella-triangolo
  • Contatti a specchio e meccanicamente collegati

Reliable in all networks

The electronic system within the AF contactor rectifies the AC or DC control circuit voltage to a DC control voltage that is applied on the coil. The contactor is safely operated in an always optimized condition making it virtually noise free.

Four coils for the entire voltage range

The AF contactor features both AC and DC support. With the complete AF contactor range, functionality is improved. Still, the total number of product variants compared to a conventional range is reduced by 90%. Only four coils are required to cover 24 V AC, 20 V DC-500 V AC/DC.

Wide control voltage range

With conventional contactor technology, different contactors were needed for different network voltages. Thanks to the wide operating range of the AF contactor it can operate just as well in Europe as in Asia or North America. The core coil of the AF contactor range covers 100-250 V, AC/DC and 50/60 Hz.

Built-in surge suppression

With conventional contactor technology it is recommended to use an external surge suppressor, an accessory that could cost as much as half the contactor itself. With the AF technology the surges are handled by the contactor itself and the surge never reaches the control circuit. Neither the surge suppressor nor the actual surge has to be considered anymore. One less product and one less complication to worry about.
