FAQs
The 1SBL921074R8810 is a three-pole block contactor with 3 NO main contacts and 1 NO auxiliary contact, rated for 690 V and up to 27 A in AC-1 duty and 18 A in AC-3. Its coil accepts 230–240 V at 50 Hz or 240–260 V at 60 Hz, aligning with common PLC and drive outputs for seamless integration in 3-phase motor circuits.
Wire the single auxiliary NO contact in parallel or series with control logic as required to provide feedback or interlocking signals. The device uses screw terminals with IP20 protection, allowing safe, straightforward connections inside standard control panels. Ensure proper torque (1 N·m) on auxiliary and main terminals during installation to maintain reliability.
Yes, within its specified ambient range. The ABB contactor operates in environments from -25 to 55 °C with thermal overload relay fitted, and from -40 to 70 °C without it. For high-altitude or demanding locations, derating may be necessary, but the unit is designed for rugged industrial use and maintains performance across common manufacturing conditions.
The product carries CE and UL certifications, with additional RoHS compliance and regional declarations (CCC, CQC). These certifications support global deployment, allow customers to meet regulatory requirements in diverse markets, and ensure safety and reliability in electrical protection and motor-control applications.
The integrated auxiliary contact, compact footprint, and robust mechanical timing (9–16 ms energize/de-energize) minimize wiring complexity and downtime. With rated IP20 protection and reliable switching (AC-1/AC-3), maintenance intervals are extended, reducing total cost of ownership through fewer replacement parts, smoother automation integration, and consistent motor-control performance.
