ABB AF09ZB-30-10RT-23 3-Pole Contactor for Railway Applications, 100-250V 50/60Hz, Enhanced Energy Efficiency and Compact Design

The ABB AF09ZB-30-10RT-23 3-pole contactor is engineered to meet the rigorous demands of railway rolling stock applications, ensuring reliable performance in both passenger and driver cabins, especially in environments like tunnels or undergrounds. Designed for controlling 3-phase motors and power circuits up to 690 V AC and 220 V DC, this contactor enhances installation compactness with its reduced dimensions and side-by-side mounting capability, saving up to 15% in width. It 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. The device excels in fire and smoke safety, complying with EN 45545-2 (HL2, HL3 hazard levels). Its lightweight design and 68% reduction in coil energy consumption contribute to energy efficiency. The electronic coil interface accommodates significant DC voltage fluctuations and supports various Uc DC control voltages, including sinusoidal AC 50/60 Hz control supplies. The AF09ZB-30-10RT-23 features a built-in auxiliary contact and Ring-Tongue Terminals, managing motors up to 4 kW / 400 V AC (AC-3) or 5 hp / 480 V UL, and switching power circuits up to 25 A (AC-1) or 25 A UL general use. With AF technology, it offers a wide control voltage range (100-250 V 50/60 Hz and DC), reducing panel energy consumption and ensuring reliable operation in unstable networks. Built-in surge protection and a block type design allow for easy extension with auxiliary contact blocks and a variety of accessories.
