ABB 1SFN010716R1001 Auxiliary Contact Block - IP20

The module delivers a single NC auxiliary contact, which translates into simplified feedback signaling for PLCs and motor control logic. This minimal-contact design reduces wiring complexity and associated termination points, decreasing installation time and panel space required. With a compact footprint (65 mm wide, 12 mm deep, and 74 mm high) and a light 0.04 kg weight, it fits neatly alongside ABB AF/UA contactors, enabling scalable panel design and easier future upgrades. Power loss remains low at 0.15 W per pole, preserving panel thermal budgets and reducing cooling requirements in dense assemblies. The auxiliary circuit supports flexible wiring (1x 0.75–2.5 mm² or 2x 0.75–2.5 mm² ferrules; rigid 1–4 mm²), simplifying field connections and inventory management. Screw terminals and a tightening torque of 1 N·m ensure robust, vibration-tolerant terminations in industrial environments. Wire-stripping length of 9 mm accelerates clean terminations, while IP20 protection provides dependable operation inside control cabinets. Compatibility with a wide range of ABB contactors (AF400–AF2850, GAF series, UA and A family) reduces the need for extensive accessory kits, lowering total-install costs. The product’s certifications and declarations—CE, RoHS, UKCA, and cULus where applicable—support global compliance programs and supplier audits. The included data sheets and CAD drawings enable precise integration into engineering workflows, improving change management and install predictability. Packaging and transport metadata (bag, 1 piece) simplify stocking and reorder cycles, minimizing stockouts in procurement workflows. In practice, this auxiliary block meaningfully enhances reliability and uptime in protection and control subassemblies while keeping maintenance overhead low.
