ABB AF09ZB-30-10-22

The AF09ZB 3-pole contactor is engineered to meet modern railway standards, making it suitable for installation in driver cabins or passenger compartments—especially in trains operating in tunnels or underground environments.

It is primarily used to control three-phase motors and power circuits with voltage ratings up to 690 V AC and 220 V DC. Its compact design supports side-by-side installation with no spacing, allowing for up to 15% reduction in width, optimizing space in tight electrical cabinets. The device operates reliably in extreme temperature conditions, from -40 °C to +70 °C.

AF09ZB complies with key international railway and industrial standards, including:

• IEC 60947-4-1
• IEC 60947-5-1
• IEC 60077-1 and 60077-2
• Relevant sections of EN 50155
• Shock and vibration resistance as per IEC 61373, category 1, class B

It also meets high safety requirements for fire and smoke protection, achieving HL2 and HL3 hazard levels under EN 45545-2, even when installed in grouped configurations.

Designed for energy-efficient rail systems, this contactor features a lightweight construction and reduces coil power consumption by up to 68% during operation.

The integrated electronic coil interface accommodates a wide range of control voltages, tolerating significant DC voltage fluctuations. It is compatible with multiple DC control voltages commonly used in battery-powered systems and also supports sinusoidal AC control inputs (50/60 Hz) within the Ucmin to Ucmax range.
