ABB 1SFL991074R3611 Block Contactor - CE/UL Certified

Three-pole block construction with three main normally open contacts and one NO plus one NC auxiliary contact provides integrated motor control in a compact footprint. This feature reduces wiring complexity and panel footprint, delivering faster onboarding and easier troubleshooting. It is well suited for starting and stopping three-phase conveyors, pumps, and fans in industrial plants, minimizing space while maintaining reliable signaling to downstream controllers. AC-1 and AC-3 rating coverage ensures reliable operation across a broad range of loads and voltages. The AX150-30-11-36 style ratings translate into predictable torque and reduced contact wear, extending service intervals in harsh environments. In practice, engineers can select this device for 690 V networks up to 190 A AC-1 or up to 150 A AC-3 at common voltages, simplifying spec sheets and procurement. Low power loss per pole at rated operating conditions, 2.7 W, reduces heat generation inside the switchgear and lowers cooling requirements. The business impact is lower energy consumption and longer cabinet life, especially in high-duty cycles. This makes it attractive for continuous operation equipment such as fans, pumps, and material handling lines. Compact dimensions and weight support easier installation: width 102 mm, depth 123.5 mm, height 148 mm, net weight 1.9 kg. This enables clean, space-efficient panel layouts and straightforward retrofits alongside existing ABB AX90–AX150 series devices. The unit’s standard mounting and compatibility with common DIN-rail or panel mounting practices accelerate integration and spare part alignment. Altitude tolerance up to 3000 m without derating, plus robust environmental and compliance foundations—RoHS, REACH, WEEE B2B—help ensure global deployment. Documentation and data access are seamless via datasheets (1SBC100214C0202), operation manuals (AX 90–150 A), and CAD drawings, enabling design-in confidence and faster time-to-commission.
