ABB 1SBL321074R8121 Block Contactor - UL Certified
Part Number: 1SBL321074R8121
Quick Summary
ABB 1SBL321074R8121 Block Contactor enables reliable 3‑phase motor control in industrial power circuits up to 690 V AC. Too often projects suffer downtime and wiring challenges when fan-out and coil ratings don’t align with the application. This model addresses those pain points with a compact block design, built-in auxiliary contacts, and a wide accessories lineup. It is UL certified and RoHS compliant, with a REACH declaration and other global conformance documents that support procurement in regulated markets. The AX40 series is also designed for high-altitude installations without derating, offering predictable performance in warehouses, processing plants, and outdoor enclosures. Coupled with CAD files and add-on blocks, it accelerates engineering, reduces panel space, and lowers total cost of ownership.

4755 >> Contactors
Three main normally open contacts (NO) enable direct 3‑phase switching in a single device. This minimizes wiring complexity, reduces panel depth, and speeds commissioning in motor control centers and machine drives. The unit includes two NO and one NC auxiliary contacts, supporting interlocking and PLC feedback for safer start/stop logic and streamlined fault diagnostics in line automation. The AC-operated control circuit simplifies integration with standard plant electronics, eliminating the need for DC supplies in many automation panels and reducing wiring costs. The compact block design, with a width of 66 mm, depth of 108 mm, and height of 90 mm and a weight of 0.715 kg, saves panel space and eases handling; front or side mounting options and add-on auxiliary blocks provide wiring flexibility for crowded switchgear and future expansions. Operation up to 3000 m altitude without derating ensures reliable performance in high‑altitude facilities, while RoHS and REACH compliance reduces regulatory risk. Certifications and data support—UL certificate, CMRT, TSCA declarations, and WEEE B2B classification—facilitate global procurement, and CAD 2D/3D data speeds integration into engineering workflows.
