The ABB AF52-30-00-11 is a 3-pole contactor designed for controlling power circuits up to 690 V AC and 220 V DC. It is ideal for managing 3-phase motors and non-inductive or slightly inductive loads. Featuring an electronic coil interface, this contactor accepts a wide control voltage range (24-500 V 50/60 Hz or 20-500 V DC) with just four coils, simplifying global applications. Built-in surge protection eliminates the need for additional suppressors. The AF... series 1-stack 3-pole contactors are of a block type design and offer compatibility with front and side-mounted auxiliary contact blocks..This ABB AF52-30-00-11 is a 3-pole contactor with 3 normally open main contacts. It operates on a main circuit voltage of up to 690 V and a control circuit voltage ranging from 24-60 V AC (50/60 Hz) and 20-60 V DC. The rated operational current for AC-1 is 100 A at 690 V (40°C), 80 A at 690 V (60°C), and 70 A at 690 V (70°C). For AC-3, it handles 53 A at 415 V, 440 V, 380/400 V, and 220/230/240 V (all at 60°C), and 45 A at 500 V (60°C), and 35 A at 690 V (60°C). The maximum electrical switching frequencies are 600 cycles/hour for AC-1, 150 cycles/hour for AC-2/AC-4, and 1200 cycles/hour for AC-3. The conventional free-air thermal current (Ith) is 105 A (open contactors at 40°C). It features screw terminals and has a net product weight of 0.97 kg. The maximum permissible operating altitude is 3000 m without derating. It is RoHS compliant according to CE Directive 2011/65/CE.
