1SBL136561R2100 ABB AF09ZB-22-00-21 – AF09ZB 9A 2NO 2NC AF Series Contactor No Auxiliary Contact

Why Choose the ABB 1SBL136561R2100 AF09ZB-22-00-21 Contactor?

The ABB 1SBL136561R2100, also designated AF09ZB-22-00-21, is a compact and energy-efficient 4-pole contactor developed for reliable power switching in railway rolling stock and demanding industrial applications. As part of the ABB AFZB railway contactor range, it features two normally open and two normally closed main contacts, providing a flexible switching arrangement for non-inductive, slightly inductive and motor loads.

The AF09ZB-22-00-21 incorporates ABB electronic coil technology with a wide 24–60 V AC 50/60 Hz and 20–60 V DC control voltage range. The electronic coil interface manages substantial control-voltage variations, reduces coil energy consumption and supports reliable operation in unstable electrical networks. Integrated surge suppression further simplifies installation by removing the need for an additional external coil suppressor.

With a rated operational current of 9 A under AC-3 at 400 V, motor switching capability up to 4 kW at 400 V AC and an AC-1 rating of 25 A at 690 V, the AF09ZB-22-00-21 provides dependable switching in a compact package. Screw terminals, robust construction and compliance with key railway standards make it particularly suitable for rolling stock, auxiliary power systems and industrial electrical installations.
