Three-pole construction with three main NO contacts and one NO plus one NC auxiliary contact enables simultaneous switching of power and control lines, reducing panel wiring and installation time for machine tools and conveyors. This directly lowers installation costs and improves startup reliability in rolling production lines. Coil operating limits and control voltage are designed for compatibility with standard 50/60 Hz supply (Uc 380–400 V at 50 Hz, 400–415 V at 60 Hz). This keeps heat generation low at 2.7 W per pole, improving efficiency and reducing cooling needs in control cabinets. In practice, this supports plug-and-play integration with common motor starters and direct-on-line schemes in plants across packaging, materials handling, or process lines. Electrical endurance is built into the design with IEC 60947-4-1 compliance, offering Ie AC-1 up to 145 A at 40 °C and Ie AC-3 up to 96 A at 415 V, along with Pe values up to 55 kW and a robust impulse withstand of 8 kV. Rated making and breaking capacities ensure safe motor starts and stops in demanding applications such as pumps and fans. Mechanical durability is rated at 10 million cycles, with a maximum switching frequency of 3600 cycles per hour. The unit uses cable clamp terminals for secure wiring, IP40 protection, and a compact footprint that simplifies mounting and service access, helping reduce maintenance downtime and extend service life in automation lines. Designed for straightforward replacement in existing AX95/AX115/AX150 installations and compatible with standard packaging, the 1SFL431074R8511 supports rapid field replacement and predictable lead times.
