1SBL136560R2100 ABB AF09ZB-22-00RT-21 4 Pole 2NO 2NC Contactor 24-60V 50/60Hz 20-60VDC Ring-Tongue Terminals

Why Choose the ABB 1SBL136560R2100 AF09ZB-22-00RT-21 Contactor?

The ABB 1SBL136560R2100, also designated AF09ZB-22-00RT-21, is a compact and robust 4-pole contactor developed for railway rolling stock and demanding industrial power-switching applications. As part of the ABB AF 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-22-00RT-21 incorporates ABB AF electronic coil technology with a wide 24–60 V AC 50/60 Hz and 20–60 V DC control voltage range. This technology manages significant control-voltage variations, reduces coil energy consumption and provides reliable operation in unstable electrical networks. Integrated surge protection further simplifies installation by eliminating 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, the AF09ZB-22-00RT-21 provides dependable switching performance in a compact package. Ring-tongue terminals, enhanced shock and vibration resistance and compliance with key railway standards make it particularly suitable for rolling stock, traction equipment and other demanding electrical installations.
