150 A across-the-line switching with wide-coil compatibility
The ABB AF110-30-11-70 is a 150 A, 3-pole non-reversing contactor designed for across-the-line motor starting and general power switching in industrial control panels. Its coil accepts both AC and DC control voltages from 100 V to 250 V, simplifying panel wiring where a single control transformer or battery-backed supply must serve multiple contactors.
Built-in auxiliary contacts reduce add-on hardware
The contactor ships with one normally-open and one normally-closed auxiliary contact (1 NO + 1 NC), providing feedback for PLC inputs or interlocking without a separate side-mount block. For a 150 A frame, the integrated aux contacts save DIN-rail space and reduce the parts count in the BOM — one less line item to qualify.
