The ABB 1SBL296560R2100, model AF38ZB-22-00RT-21, is a compact and energy-efficient 4-pole AC/DC operated contactor designed for reliable power switching in railway rolling stock and demanding industrial applications. As part of the ABB AF38ZB railway contactor series, it features two normally open and two normally closed main contacts together with an electronic coil interface capable of handling substantial control voltage variations.
The AF38ZB-22-00RT-21 is specifically engineered to meet demanding rolling stock requirements, including resistance to shock and vibration and enhanced fire and smoke performance. Its compact design supports space-efficient side-by-side installation, while ring-tongue terminals provide secure electrical connections suited to applications exposed to vibration and demanding operating conditions.
With a rated operational current of 55 A at 690 V AC under AC-1 at 40 °C and a motor switching capability of up to 11 kW at 400 V AC under AC-3, the AF38ZB-22-00RT-21 provides flexible power control for railway and industrial systems. Its wide-range electronic coil operates from 24–60 V AC at 50/60 Hz or 20–60 V DC, helping maintain reliable operation where control supplies are subject to significant voltage fluctuations.
ABB AF38ZB contactors are engineered for electrical installations where dependable switching must be maintained despite challenging environmental and supply conditions. The electronic coil interface handles substantial DC voltage fluctuations, including control voltages commonly associated with railway battery supplies, while also accepting sinusoidal AC 50/60 Hz control supplies within the specified voltage range.
The AF38ZB-22-00RT-21 combines this flexible coil technology with a four-pole 2 NO + 2 NC contact arrangement, ring-tongue terminals and railway-qualified construction. Its resistance to shock and vibration, broad operating temperature range and enhanced fire and smoke performance make it particularly suitable for onboard railway equipment and other demanding power switching applications.
