4755 >> Contactors
The 3 main NO contacts and 1 auxiliary NO contact simplify wiring and reduce enclosure footprint, delivering a faster, cleaner installation with fewer components. This translates to lower assembly time and a reduced risk of miswiring in panel builds, improving overall reliability on conveyors and machine tools. The coil operates at 190 V with 50 Hz or 220 V with 60 Hz, enabling seamless integration with common control circuitry without extensive rewiring, which lowers commissioning time and post-install support. Rated for main circuits up to 690 V and auxiliary circuits at the same voltage, the device supports wide industrial applications while maintaining consistent operating performance. Weighing 0.667 kg and occupying a compact 54 mm width by 90 mm depth and 108.3 mm height, it fits tight control cabinets and modular panels where space is at a premium. IP20 protection covers both main and auxiliary terminations, ensuring safe operation in standard indoor environments. The device supports a wide operating temperature range and is compatible with add-on auxiliary contact blocks for front or side mounting, enabling future expansion without replacing the base unit. With 2.5 W per pole for AC-1 and 0.9 W per pole for AC-3, energy efficiency is improved while maintaining robust switching performance. The contactor is engineered for rapid switching with operate times typically between 7 and 21 ms, and a maximum mechanical switching rate of 3600 cycles per hour, supporting high-demand automation scenarios. Tightening torques of 1 N·m for auxiliary and control circuits and 2.3 N·m for main circuits ensure secure connections in vibration-prone environments.

FAQs
Yes. The 1SBL281074R3610 is designed for main circuits up to 690 V AC and 50/60 Hz control, with screw terminals and IP20 protection, making it suitable for common panel layouts and standard control cabinets used in machine tools, conveyors, and fans.
For AC-3 operation at 415–690 V, the device supports up to 32 A nominal current per pole, with an adjustable operate time in the range of roughly 7–14 ms (coil de-energize to NC closing) and 8–21 ms (coil energize to NO closing). This enables reliable starting of 3-phase motors with moderate inrush demands.
The model carries CE Declaration of Conformity, UL/CSA certification, and CB certification, along with RoHS and REACH declarations. These certifications underpin global regulatory compliance, support market access, and reassure buyers that the device meets essential safety and environmental standards for industrial automation.
Installation uses screw terminals for main and auxiliary circuits, with a compact width of 54 mm and 90 mm depth suitable for tight panels. The design supports add-on auxiliary contact blocks for front or side mounting, enabling scalable expansion without replacing the base contactor as control logic evolves.
The device offers IP20 protection and a robust mechanical switching capability up to 3600 cycles per hour. With ambient operating ranges from -25 to 70 °C and a rated insulation voltage of 690 V, it is suited for standard indoor automation environments, though a thermal overload relay can be added if protection against overheating is required in high-duty cycles.
