ABB AF26ZB-30-00RT-21 3-Pole Contactor for Railway Applications, 24-60V 50/60Hz, Compliant with IEC and EN Standards, Energy Efficient Design

The ABB AF26ZB-30-00RT-21 is a robust 3-pole contactor designed to meet the stringent requirements of railway rolling stock standards, making it ideal for installation in passenger or driver cabins of trains frequently operating in tunnels or underground environments. This contactor is engineered to control 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. It adheres to key rolling stock standards, including IEC 60947-4-1, IEC 60947-5-1, IEC 60077-1/-2, and parts of EN 50155, while also conforming to IEC 61373 for shock and vibration resistance. The device excels in fire and smoke behavior, complying with EN 45545-2 standards for hazard levels HL2 and HL3. With a lighter design, it reduces train energy consumption and requires 68% less coil energy during operation. The electronic coil interface accommodates large DC voltage fluctuations and supports various Uc DC control voltages, including sinusoidal AC 50/60 Hz control supplies. The AF26ZB-30-00RT-21 features a wide control voltage range (24-60 V 50/60 Hz and 20-60 V DC), built-in surge protection, and a block-type design that can be easily extended with auxiliary contact blocks and a range of accessories. It is capable of controlling motors up to 11 kW / 400 V AC (AC-3) or 15 hp / 480 V UL and switching power circuits up to 45 A (AC-1) or 45 A UL general use, ensuring reliable performance even in unstable networks.
