ABB AF09ZB-30-10RT-21 3-Pole Contactor for Railway Rolling Stock Applications, 24-60V AC/DC, Energy-Efficient with Built-In Surge Protection and Ring-Tongue Terminals

The ABB AF09ZB-30-10RT-21 is a robust 3-pole contactor designed to meet the demanding standards of railway rolling stock applications. Ideal for installation in passenger or driver cabins, this contactor is perfect for trains frequently operating in tunnels or underground environments. It efficiently controls 3-phase motors and power circuits up to 690 V AC and 220 V DC, offering a compact solution with reduced dimensions and side-by-side mounting that requires 15% less width. The contactor adheres to key rolling stock standards, including IEC 60947-4-1, IEC 60947-5-1, IEC 60077-1/-2, and EN 50155, and withstands shocks and vibrations as per IEC 61373 cat. 1, class B. It also meets the highest fire and smoke behavior standards, complying with EN 45545-2 (HL2, HL3 hazard levels). The AF09ZB-30-10RT-21 is energy-efficient, requiring 68% less coil energy consumption, and features an electronic coil interface that handles large DC voltage fluctuations. It supports a wide range of auxiliary contact blocks for versatile front and side mounting. With a built-in auxiliary contact and Ring-Tongue Terminals, it controls motors up to 4 kW / 400 V AC (AC-3) or 5 hp / 480 V UL and switches power circuits up to 25 A (AC-1) or 25 A UL general use. The AF technology ensures a wide control voltage range (24-60 V 50/60 Hz and 20-60 V DC), managing voltage variations and reducing panel energy consumption, while built-in surge protection enhances reliability. The block-type design allows for easy extension with add-on auxiliary contact blocks and a wide range of accessories.
