Abb four-pole contactor 70A 4P 4NA 24-60VCA/DC AF40400011

A contactor is a device for closing and opening electrical circuits, mostly high voltage circuits, by remote control.

 

IEC 17-3 defines a contactor (contactor) as a device capable of interrupting or establishing current within a circuit. To do this, the device opens and closes contact channels between the system and the power structure. In short, a kind of switch to be used for all eventualities.


 

Overview:

• AF40 contactors ... AF80 four-pole are mainly used for controlling non-inductive or slightly inductive loads (e.g., resistance furnaces...) and generally for controlling power circuits up to 690 VAC and 440 VDC. These contactors have a block design with 4 main poles.
  
   

Advantages:

• They can handle wide variations in control voltages
• Reduced switchboard power consumption
• Very distinct closing and opening
• They are able to tolerate short voltage dips and voltage dips (SEMI F47-0706 conditions of use upon request)
• Built-in surge suppression and do not require additional surge protectors
• Additional auxiliary contact blocks with front or side mounting and a wide range of accessories.
