Feature → Business Impact → Application: Three main NO contacts (3P) provide reliable power switching for three‑phase motors, enabling clean, synchronized start/stop sequences and reduced electrical noise. This translates to improved machine uptime and lower maintenance costs in manufacturing lines. Feature → 690 V insulation and 1000 V rating where applicable ensures compliance across global installations, minimizing rework when equipment is deployed internationally. Application: Suitable for high‑voltage motor control in packaging, extrusion, and process lines where regulatory adherence and long service life matter. Feature → Auxiliary NO/NC contact set (1 NO + 1 NC) supports integrated interlocking and signaling, simplifying control logic and reducing wire routing complexity. Application: Ideal for compact control panels in material handling and conveyance systems. Feature → AC‑3 rated performance (up to 205 A at 415 V, 170 A at 690 V) provides controlled motor starting with high mechanical durability, supporting long‑term production reliability. Application: Heavy‑duty conveyors and fans where frequent switching occurs. Feature → Mechanical durability of 5 million cycles and rated short‑time withstand current up to 1200 A (Icw) at 40 °C enables resilience under peak loads. Application: Critical in applications with intermittent peak demand like metalworking and plastics processing. Feature → Compact dimensions (111.5 mm width, 162.3 mm depth, 196 mm height) and weight around 3.2 kg facilitate easy installation and space optimization in control cabinets. Application: Ideal where panel space is constrained and retrofit projects require minimal footprint impact. Feature → Broad compatibility with standard motor starters, overload relays, and protective devices (DIN rail or panel mounting), streamlining procurement and reducing project lead times. Application: OEMs and system integrators benefit from faster commissioning and consistent performance across machines.

FAQs
The 1SFL501074R8311 is a three‑pole block contactor designed for main circuits up to 1000 V insulation and 690 V rated operation. It features a main circuit with bars for terminals and an auxiliary NO/NC contact, allowing straightforward wiring and reliable integration with standard overload relays and motor starters in 50 Hz environments.
AC‑3 ratings vary by voltage: at 415 V, Ie is 205 A with a corresponding Po ≈ 110 kW; at 690 V, Ie is 170 A with Po ≈ 132 kW. The device also supports up to 8 x Ie as rated breaking capacity and up to 10 x Ie for making capacity, enabling controlled motor starting for heavy loads.
Yes. The contactor is designed for compatibility with common ABB motor protection components and is listed with CE declarations, UL/cULus certification, and RoHS compliance. This ensures reliable operation across global markets and simplifies regulatory documentation in panel builds.
The unit uses main circuit bars for terminals and has compact dimensions: 111.5 mm width, 162.3 mm depth, and 196 mm height, with an approximate net weight of 3.2 kg. Plan for panel space, proper ventilation, and ensure ambient temperatures remain within −25 to 70 °C depending on nearby relay configurations to avoid derating.
With a mechanical durability of about 5 million cycles and a low coil power loss (~5 W per pole), you gain reduced maintenance intervals and lower energy consumption. The built‑in auxiliary contact supports simpler wiring and diagnostics, shortening replacement time and improving system availability, which translates into tangible operating expense savings.
