Why Choose the ABB AF45-22-00 100–250 V AC/DC Contactor?
The ABB AF45-22-00, order code 1SBL337501R7000, is a robust 4-pole AC/DC-operated contactor designed for reliable switching of industrial power circuits. As part of the advanced ABB AF contactor series, it uses electronically controlled coil technology to provide dependable operation across a wide control voltage range.
This contactor features 2 normally open (NO) and 2 normally closed (NC) main poles with no built-in auxiliary contacts. The mixed main-pole arrangement provides flexible switching of separate industrial circuits, while ABB's AF electronic coil interface helps accommodate control-voltage variations and incorporates surge suppression for the control circuit.
With a wide 100–250 V AC/DC control voltage range and an AC-1 rated operational current of 70 A at up to 40 °C, the AF45-22-00 is suited to industrial machinery, power distribution and automation systems. Its compact block-type construction, screw terminals and panel-friendly dimensions make it practical for integration into industrial electrical control equipment.
