Three main poles with a block design and an AC-operated control circuit deliver dependable motor switching, reducing contact wear and arcing during start-up. This translates to longer service life for 3-phase motors and lower maintenance costs in demanding applications such as pumps and compact conveyors. Ith rated at 125 A (Θ=40 °C open-air) combined with Ie up to 115 A at 690 V provides robust capability for inrush and continuous loads in typical plant environments. AC-3 ratings up to 65 A at 415–690 V and Pe up to 37 kW enable efficient drive of motors in fans, pumps, and conveyors without over-sizing. IP20 coil protection and IP10 main terminals simplify installation in control panels while preserving safety. Maximum electrical switching frequency of AC-1/AC-3 at 600 cycles per hour and 3600 mechanical cycles support high-throughput industrial cycles. A compact footprint (70 mm W × 110 mm D × 108 mm H) with screw terminals, 1 N·m coil torque, and 4 N·m main-terminal torque reduces wiring time and promotes reliable termination. The option for add-on auxiliary contacts and side mounting expands compatibility with control architectures, while a 1-piece MOQ and CAD-friendly dimensions streamline procurement and engineering. Clear product documentation, including Data Sheet, Instructions, and CAD drawings, support rapid specification and compliant integration in modern automation systems.

FAQs
Install the contactor on a suitable panel surface or DIN rail-compatible mounting area as per the enclosure design. Connect the main circuit to the three NO main contacts using appropriate conductors, tighten main terminals to 4 N·m, and connect the control circuit coil with 1 N·m torque. Use the coil terminals with IP20 protection and ensure the main terminals are IP10 protected. If an auxiliary contact block is added, mount it on the side according to the accessory guide. Verify the 50 Hz or 60 Hz coil voltage (220–230 V or 230–240 V) matches the supply and confirm proper insulation distances.
For AC-1 operation at 690 V a rated operational current Ie is 115 A at 40 °C and 80 A at 70 °C. At 220–240 V AC, Ie is 95 A at 55 °C. For AC-3 operation, Ie is 65 A at 415–440 V and 65 A at 380–400 V, with 55 °C ambient ratings. The device supports Pe up to 37 kW at several high-voltage levels (e.g., 415–690 V). This data helps you select the correct motor size and ensure knock-on effects for short-time withstand and thermal limits are accounted for in your protection scheme.
Yes. The ABB 1SBL371074R8000 is designed for 3-phase motor control up to 690 V AC, with main circuit rated for heavy-duty switching and a maximum breaking capacity of 630 A at 690 V. It supports AC-1 and AC-3 operations at relevant voltage levels, and its 125 A Ith protection provides a comfortable margin for many conveyor and pump applications. The design also remains compatible with add-on auxiliary contacts for expanded control logic in automation lines.
The device carries CE and UL certifications, with CCC, CQC, and RoHS/REACH declarations, reflecting compliance with global safety, environmental, and performance standards. These certifications support safe operation in regulated facilities, simplify acceptance tests, and enable cross-border procurement. For regulated industries such as food processing or water treatment, regulatory alignment reduces risk during audits and accelerates project timelines.
The contactor supports 600 electrical switching cycles per hour (AC-1/AC-3) and 3600 mechanical cycles, indicating suitability for frequent on/off duty in automation lines. Power loss is 6.5 W per pole for AC-1 and 1.5 W per pole for AC-3, so consider thermal management and ambient temperature in your enclosure. Regular inspection of screw terminals and coil connections, plus periodic test operation, will help maintain reliability and extend life in environments up to 70 °C and 3000 m altitude without derating.
