Power contactor AC-1 500 A / 690 V / 40°C 3-pole, Uc: 96-127 V AC (50-60 Hz) / DC F-SPS input 24 V DC Drive: electronic Auxiliary contacts 2 S + 2 Ö Main circuit: rail Control and auxiliary circuit: screw connection. Contactor SIRIUS 3RT14 for switching high-power resistive loads, specifically designed and certified for easy setup of safety-related applications up to SIL CL 3. The 3RT1 contactors are part of the SIRIUS modular system with optimally coordinated products. They impress with high performance while maintaining a compact design and high contact reliability. They can be combined in various ways with other components in the load branch. The contactors provide the appropriate connection to the control system for safety-related applications in the form of a fail-safe PLC input. Pre-assembled auxiliary switches reduce the complexity of your setup. The 3RT1 contactors are climate-resistant and globally approved (e.g., IEC and UL/CSA). The 3RT contactors with fail-safe control are available in various sizes and a wide power range. They feature an AC/DC wide voltage range and a PLC control input. In the main circuit, the devices can be connected via rails or frame terminals. There is a wide range of accessories available for these contactors, such as wiring kits that significantly reduce wiring effort, auxiliary switches, or terminal covers. Simple, efficient, always up-to-date - the SIRIUS modular system.
