Contactor AF52

3-pole AF contactors

New AF contactors are equipped with innovative AF technology. Electronic coil control offers many benefits over traditional alternatives. Combined with ABB’s broad product portfolio, building an optimal configuration is easy.

Benefits

• The relatively narrow list of products enables the optimisation of logistics and makes product management easier


• The products are universal: the 100–250 V AC/DC-controlled coil is compatible with all standard mains voltages


• Energy consumption reduced by 80% as compared to traditional coil control solutions


• The high control voltage change resilience provided by the AF technology guarantees uninterrupted operation


• AFz solution connected directly to logic control without supplementary relays

Properties

• Up to 560 kW–400 V AC-3 and 2650 A–690 V AC-1


• The 4 coil voltage ranges cover 24–500 V AC and 20–500 V DC


• Screw, spring and ring connectors


• Internal control circuit interference protection; no interference in the control circuit when the contactor opens


• Ready-for-use connector and fastener sets enable the easy, quick and reliable assembly of reversing and star-delta starters.


• Mirror and mechanically connected auxiliary contactors.
