Why Choose the ABB AF75-22-00 20–60V DC Contactor?
The ABB AF75-22-00, order code 1SBL417501R7200, is a 4-pole block contactor designed primarily for controlling non-inductive or slightly inductive loads and general industrial power circuits. This exact version features ABB's electronic coil interface with a wide 20–60 V DC rated control-voltage range.
The AF75-22-00 has 2 normally open + 2 normally closed main poles and no built-in auxiliary contacts. It provides an AC-1 operational current rating of 125 A at 690 V and 40 °C, making it suitable for resistance heating, lighting and other four-pole industrial switching duties.
ABB's AF electronic coil technology manages significant control-voltage variations while reducing power consumption and providing distinct, quiet opening and closing. This 20–60 V DC version is polarity sensitive, requiring A1 to be connected to positive and A2 to negative, and can withstand short control-supply interruptions or voltage dips of up to approximately 20 ms.
