ABB AF38ZB-22-00RT-23

Engineered for the demanding requirements of railway rolling stock, the ABB AF38ZB-22-00RT-23 4-pole contactor is a high-performance solution designed for reliability in harsh environments, including tunnels and underground operations. This contactor is primarily used for controlling non-inductive or slightly inductive loads and power circuits up to 690V AC and 440V DC.

Featuring ABB's innovative AF technology, this contactor offers a wide control voltage range (100-250V AC/DC), ensuring stable operation even with large voltage fluctuations in battery-supplied networks. Its electronic coil interface also accepts sinusoidal AC 50/60 Hz control supplies, providing versatility. The design prioritizes space-saving with a reduced dimension and side-by-side mounting capability that requires 15% less width without spacing, all while operating reliably from -40°C up to +70°C.

The AF38ZB-22-00RT-23 complies with all major rolling stock standards, including IEC 60947-4-1, IEC 60947-5-1, IEC 60077-1/-2, and applicable parts of EN 50155, with shocks and vibration withstand conforming to IEC 61373 category 1, class B. It also meets the highest fire and smoke behavior standards, complying with EN 45545-2 (HL2, HL3 hazard levels). By reducing coil energy consumption by up to 68% and featuring a lighter design, this ABB contactor contributes to reduced train energy consumption. It can be easily extended with a wide range of front and side-mounted auxiliary contact blocks.
