ABB AF16ZB-30-10RT-21 3-Pole Contactor, 30A, 20-60VDC Coil – Ideal for Railway Rolling Stock Applications

The ABB AF16ZB-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 saves up to 15% in width. Compliant with key railway standards such as IEC 60947-4-1, IEC 60947-5-1, IEC 60077-1/-2, and EN 50155, it withstands shocks and vibrations as per IEC 61373 cat. 1, class B. The AF16ZB-30-10RT-21 excels in fire and smoke safety, adhering to EN 45545-2 standards for hazard levels HL2 and HL3. Its lightweight design reduces train energy consumption, while the electronic coil interface manages large DC voltage fluctuations, accommodating various Uc DC control voltages and sinusoidal AC 50/60 Hz control supplies. This contactor features a wide control voltage range (24-60 V 50/60 Hz and 20-60 V DC), ensuring reliable operation even in unstable networks. Built-in surge protection enhances its compactness, and the block type design allows for easy extension with auxiliary contact blocks and a variety of accessories. With a built-in auxiliary contact and Ring-Tongue Terminals, it controls motors up to 7.5 kW / 400 V AC (AC-3) or 10 hp / 480 V UL, and switches power circuits up to 30 A (AC-1) or 30 A UL general use, making it a versatile and efficient choice for modern railway systems.
