1SBL177501R1100

The ABB AF16-22-00-11 Contactor, Part No. 1SBL177501R1100, is a compact 4-pole block contactor designed for industrial switching applications where both normally-open and normally-closed power contacts are required. Its 2 NO + 2 NC main pole arrangement makes it suitable for control, transfer, heating, HVAC, automation, OEM machinery, and general power-switching circuits.

It uses ABB’s AF electronic coil technology, providing a wide control-voltage range of 24–60 V AC at 50/60 Hz and 20–60 V DC. This helps tolerate control-supply variations and simplifies panel design compared with fixed-voltage coils.
