The 3-pole block contactor architecture enables reliable motor control up to 690 V AC, delivering robust switching performance with a compact footprint. This translates to reduced panel space and easier installation, which lowers wiring complexity and labor costs in packaging lines, conveyors, and metalworking applications. At 690 V, the rated operational current for AC-3 is 43 A (55 °C), ensuring compatibility with common fan, pump, and compressor loads while preserving switch life. Power loss is minimized with 6.5 W per pole for AC-1 operation and 1.5 W per pole for AC-3, contributing to cooler panels and lower energy costs over the life of the equipment. The device supports add-on auxiliary contact blocks for side mounting, improving fault diagnosis and interlock capabilities. With IP20 coil terminals and IP10 main terminals, installation reliability is enhanced in industrial environments. Dimensions (82 mm width, 110 mm depth, 108 mm height) and a net weight of 1.05 kg offer a favorable form factor for tight enclosures. Its 50 Hz and 60 Hz coil ratings (230–240 V / 240–260 V) ensure compatibility with global control systems, reducing procurement diversity and lead times. The device’s insulation voltage of 690 V and protective standards enable safe, compliant operation across a wide range of industrial installations. In practice, technicians gain faster commissioning, easier maintenance, and consistent performance under load.

FAQs
The 1SBL371074R8811 is designed for easy integration with add-on auxiliary contact blocks and supports side mounting, improving available contact configurations and enabling before-and-after interlocks. This compatibility simplifies expansion, wiring routing, and preventive maintenance, reducing downtime during motor control upgrades or panel reconfigurations.
For AC-3 operation at 690 V, the rated operational current Ie is 43 A (55 °C). At 415–440 V, Ie reaches around 65 A (55 °C) for AC-3, while AC-1 ratings can reach up to 115 A at 690 V (40 °C). The device also provides a 37 kW to 30 kW range for Pe across various voltages, aligning with motor sizing needs.
Yes, the contactor is designed for industrial environments with a broad ambient range, but de-rating may be required at elevated temperatures. Rated Short-time Withstand Current and insulation margins are specified for standard industrial conditions. For installations above specified ambient limits or high altitude, consult the datasheet to apply appropriate derating and ensure reliable operation within IEC/EN guidelines.
The model carries CE and UL/CSA approvals, RoHS compliance, and CCC/CE declarations where applicable. These certifications support regulatory compliance for global deployments and simplify supplier qualification, especially in regulated industries like food and beverage, mining, and packaging. Always verify local regulatory requirements and confirm the latest certificates from ABB for your project.
The 1SBL371074R8811 offers low power loss per pole, compact dimensions, and compatible accessory options, which reduce energy usage and enclosure space. Its robust 690 V insulation and IP ratings improve reliability, cutting preventive maintenance time and extending motor life. Overall, the upgrade can lower total cost of ownership by minimizing downtime, simplifying wiring, and ensuring consistent performance in demanding environments.
