Feature → Business Impact → Application: The 3 main NO contacts and 1 built‑in NC auxiliary contact enable clean, compact motor control with minimal wiring complexity, reducing panel space and assembly time while improving reliability in 690 V power circuits. This translates to faster commissioning, lower maintenance costs, and safer operation for conveyors, pumps, and fans in manufacturing lines. Application: Use in automated lines where space is at a premium and motor load profiles demand robust AC‑3 switching with reliable cycling. Feature → Business Impact → Application: Coil operated on 48 V at 50/60 Hz minimizes control circuit power loss (2.5 W per pole in AC‑1, 0.9 W in AC‑3), improving energy efficiency and lowering heat within control cabinets. Application: Ideal for OEMs optimizing energy use in packaging equipment and material handling systems. Feature → Business Impact → Application: Block type, 3‑pole design with front or side add‑on auxiliary blocks expands compatibility with existing control architectures. Application: Seamless integration into legacy ABB AX32‑AX40 family or similar DIN‑rail mounted systems. Feature → Business Impact → Application: IP20 protection for main, coil, and auxiliary terminals protects against dust ingress in standard manufacturing environments, reducing nuisance outages. Application: Panel installations in dry, clean rooms, and controlled environments where durability matters. Feature → Business Impact → Application: 690 V rated insulation and high breaking capacity (cos phi 0.45 at 440–690 V) support aggressive motor starting and short‑circuit resilience. Application: Heavy‑duty conveyors and pumps requiring reliable instantaneous switching. Feature → Business Impact → Application: Compact dimensions (54 mm wide, 90 mm deep, 108.3 mm high) with lightweight 0.667 kg design simplify cabinet layout and maintenance access. Application: Retrofit projects where space constraints and ease of replacement are priorities. Feature → Business Impact → Application: Wide operating temperature range and storage/gasket considerations enable deployment across varied manufacturing locales. Application: Automotive, process, and packaging environments with temperature fluctuations.

FAQs
For reliable mounting, ensure the device is wired with screw terminals, rated at IP20 protection, and comply with the 2.3 N·m tightening torque for main terminals while keeping auxiliary and control circuits at 1 N·m. Install with appropriate clearances in a clean, dry cabinet and avoid exposure to liquids or conductive contaminants. Confirm compatibility with 48 V control circuits and front or side mounting auxiliary blocks as required by your control panel design.
Key ratings include three main NO contacts and one NC auxiliary contact, rated main circuit up to 690 V and auxiliary up to 690 V, coil voltage of 48 V at 50/60 Hz, and AC‑3 current ratings around 32 A depending on voltage. The device supports high inrush demands with a maximum mechanical switching frequency of 3600 h‑1 and a short‑circuit withstand capacity suitable for standard industrial motors, delivering dependable performance for motor starters and conveyors.
Yes, the ABB 1SBL281074R8301 is designed for 690 V mains with three main NO contacts and one NC auxiliary contact, providing robust AC‑3 switching. While it offers IP20 protection, ensure installation is in a clean, dry environment or within a protected panel to avoid exposure to dust or moisture that could affect performance.
The product aligns with CE for EU conformity and carries UL safety certification, RoHS and REACH environmental compliance, as well as other declarations appropriate to block contactors. This ensures regulatory compliance for international deployments and simplifies global procurement strategies for OEMs and integrators.
The device’s low coil power loss reduces heat and energy use in control cabinets, while the compact 54 mm width saves panel space and simplifies wiring. Its durability in standard industrial environments, combined with reliable 3‑pole switching and integrated auxiliary contact, lowers maintenance intervals and spare parts costs, contributing to a favorable total cost of ownership over motor control applications.
