ABB AF205-30-11-11 Industrial Power Contactor

ABB AF205-30-11-11 is a 3-pole AF series power cont actor designed for motor starting, isolation, bypass and distribution applications up to 1000 V. It accepts a versatile control voltage: 24–60 V AC (50/60 Hz) or 20–60 V DC, enabling reliable operation with both AC and DC control circuits. The device provides three main normally open contacts and a single auxiliary contact block comprising one normally open and one normally closed contact for signaling or interlocking. ABB’s data lists UL/CSA general-use rating at 600 V AC and 300 A, with actual rated operational current AC-1 varying by voltage and temperature: 275 A at 1000 V and 40 °C, 250 A at 1000 V and 60 °C, 200 A at 1000 V and 70 °C, and 350 A at 690 V and 40 °C. These ratings reflect the AF205-30-11-11’s suitability for heavy electrical loads, including motor control, distribution and power switching, while maintaining the reliability and compatibility expected from ABB’s AF contactor family.
