ABB 1SFL647063R7122 Block Contactor - 1000 V IEC / 600 V UL

AF technology provides a wide control voltage range and built-in surge protection, delivering stable operation despite control voltage fluctuations. This minimizes nuisance tripping and reduces energy waste in panels fed from variable networks, improving overall efficiency. The design supports AC-DC control (250-500 V, 50/60 Hz and DC) with predictable coil performance, while surge suppression protects contacts and downstream electronics. Three-pole construction rated up to 1260 A AC-1 and 1210 A UL general use enables high-power switching in a single device, reducing component counts and panel complexity. The AF block contactor's block-type design simplifies wiring, improves serviceability, and supports straightforward integration with add-on auxiliary blocks for future expansion. The unit's compact footprint helps optimize enclosure space without sacrificing performance and reliability. Pre-mounted auxiliary contacts and standard ferrules are included, with easy expansion via add-on auxiliary blocks and a wide accessory ecosystem. This reduces engineering lead times, enables flexible control schemes, and minimizes field wiring errors, shortening commissioning and lowering maintenance costs. Main circuit connections via bars up to 50 mm² deliver a robust, low-resistance path with predictable torque using standard lugs at 45 N·m. Auxiliary circuit connections support multiple conductor types, including ferrules and solid or stranded conductors, ensuring reliable field wiring across diverse panel conditions. RoHS compliance and REACH registration, together with a broad certification portfolio such as CE and UL, ease regulatory approvals across regions. CAD drawings, manuals, and end-of-life guidance are readily available, supporting fast design-in and long-term maintenance, which lowers total cost of ownership for enterprise automation projects.
