AF contactors in the 100A to 370A range are robust electromechanical switching devices designed for heavy-duty motor control and power management in industrial automation systems. These contactors feature advanced arc quenching technology, typically with 3 or 4 main poles, and are rated for operational voltages up to 690V AC. They support coil voltages from 24V to 500V AC/DC, ensuring compatibility with diverse control circuits. The range includes accessories such as auxiliary contact blocks (e.g., CAL19-11), mechanical interlock units (e.g., VM19, VM140/190, VM205/265), terminal shrouds (e.g., LT140-30L, LT205-30Y, LT370-30Y), connection sockets (e.g., LL146-30, LL205-30), adapter plates (e.g., PR146-1), and interconnection bars (e.g., BEA370/T5). These components enable flexible mounting, safe wiring, and mechanical interlocking for reversing or star-delta starters. The contactors are designed for panel or DIN-rail installation, with IP20 protection for finger-safe operation.
These AF contactors are deployed in a wide range of industrial sectors, including manufacturing, water treatment, HVAC, mining, and energy distribution. They are ideal for controlling three-phase motors, resistive loads, and lighting circuits in motor control centers (MCCs), switchboards, and automation panels. The accessories, such as connection modules and terminal shrouds, facilitate integration into compact enclosures and ensure compliance with safety standards. Mechanical interlock units enable safe reversing and dual-speed motor control, while auxiliary contact blocks provide status feedback to PLCs or DCS systems. The range supports applications from conveyor systems and pumps to compressors and fans, where reliable switching under high inrush currents is critical.
All AF contactors and their accessories comply with international standards such as IEC 60947-4-1 and UL 508, ensuring global acceptance. They are fully compatible with ABB's AF contactor series, including models like AF190-30, AF205-30, AF265-30, and AF370-30. The accessories are designed for seamless integration with these contactors, maintaining electrical and mechanical ratings. For example, the VM19 and VM205/265 interlock units are specifically tailored for mechanical coupling, while terminal shrouds like LT140-30L and LT370-30Y ensure safe isolation. The CAL19-11 auxiliary contact blocks offer standard 1NO+1NC configurations, compatible with ABB's modular system. This compatibility extends to other ABB components, such as overload relays and busbar systems, simplifying system design and procurement.
