FAQs
The 1SBL321074R8810 is a 3-pole block contactor with one built-in auxiliary NO contact and screw terminals. Install with appropriate mounting in DIN rail or panel spaces, secure terminals to 1 N·m auxiliary and 2.3 N·m main torque, and follow the 54 mm width, 90 mm depth, and 108.3 mm height footprint for proper clearance. Use the 230–240 V or 240–260 V control circuit per your mains frequency (50/60 Hz).
For AC-3 operation at 690 V, the rated operational current Ie is 25 A. This should be matched with motor starting and switching requirements to ensure safe operation under typical continuous loads. The device also supports AC-1 operation up to 60 A at lower voltages, providing versatility across motor control scenarios.
Yes. It is designed for motor control up to 690 V with IP20 protection on main terminals and coil terminals, ambient conditions suitable from -25 °C to 55 °C near the device, and an altitude tolerance up to 3000 m without de-rating. The combination of rugged construction and approved certifications (CE/UL/CCC) supports reliability in industrial settings such as conveyors and pumps.
The ABB 1SBL321074R8810 family carries CE and UL certifications and CCC/CQC declarations, with RoHS and REACH compliance. It also aligns with applicable standards including IEC 60947-4-1 and IEC 60947-5-1, and supports WEEE B2B classification. These certifications help ensure regulatory compliance in global manufacturing environments.
Maintenance benefits include low power loss per pole (1.3 W for AC-3), straightforward screw-terminal wiring, and a predictable 7–21 ms operate time. Combine this with a compact 54 mm width and 0.667 kg weight for easy replacement, and the ability to mount auxiliary blocks for expansion. This translates to lower maintenance time, simpler spare parts management, and improved ROI in automated lines.
