Description

ABB AF580-30-11 1SFL617001R6811 3-Pole AC Contactor

The ABB AF580-30-11 (Article Number: 1SFL617001R6811) is a high-capacity, 3-pole block contactor from the AF Series. It is specifically engineered for large-scale industrial applications where high reliability and efficient energy management are paramount.

Product Detailed Description

The AF580 is a heavy-duty contactor featuring ABB’s advanced electronic coil interface. Unlike traditional contactors, the AF technology handles large voltage fluctuations and reduces energy consumption in the control circuit. The “30-11” designation indicates 3 Main Poles, 1 Normally Open (NO) auxiliary contact, and 1 Normally Closed (NC) auxiliary contact.

Technical Parameters

Product Advantages

• Wide Control Voltage Range: The electronic coil covers both AC and DC frequencies and handles a wide range of voltages, reducing the number of spare parts needed.
• Reduced Energy Consumption: The AF technology reduces the coil’s holding power by up to 80%, leading to cooler control cabinets and lower energy costs.
• Built-in Surge Suppression: Unlike traditional contactors that require external varistors, the AF series has integrated surge protection, preventing interference with sensitive electronic PLC outputs.
• Stable Operation: It can withstand short-term voltage dips and sags, preventing “chatter” or accidental tripping during unstable power conditions.

Important Considerations (Precautions)

• Busbar Alignment: Due to the high current (up to 800A AC-1), ensure that the connecting copper busbars are perfectly aligned and tightened to the specified torque to prevent overheating.
• Coil Polarity: While the AF coil is versatile, always verify the +/- terminals when using DC control power to ensure correct operation of the electronic interface.
• Safety Clearance: Ensure adequate “Arcing Distance” above the contactor as specified in the manual, as large contactors can exhaust ionized gases during high-current interruption.
• Weight and Mounting: This is a large device (approx. 13-15 kg). It must be mounted on a rigid backplane or a specific mounting plate rather than a standard thin DIN rail.

Product Applications

The AF580 is typically used in demanding “Big Power” industrial scenarios:

• Large Motor Starting: Direct-on-line (DOL) or Star-Delta starting for massive pumps, fans, and compressors in heavy industry.
• Power Distribution: Serving as a main breaker/contactor in automatic transfer switches (ATS) or power factor correction banks.
• Mining & Heavy Industry: Controlling high-power crushers, conveyors, and grinders.
• Wind & Solar: Acting as a primary disconnect or control switch in large renewable energy inverters and grid-tie systems.
