Power contactor AC-1 500 A / 690 V / 40°C 3-pole, Uc: 200-277 V AC (50-60 Hz) / DC F-PLC input 24 V DC Drive: electronic Auxiliary contacts 2 NO + 2 NC Main circuit: rail Control and auxiliary circuit: screw connection Contactor SIRIUS 3RT14 for switching resistive consumers with high power, specially designed and certified for easy construction of safety-related applications up to SIL CL 3. The 3RT1 contactors are part of the SIRIUS modular system with its optimally coordinated products. They impress with high power combined with a compact design and high contact reliability. They can be combined in many ways with other components in the load feeder. The contactors offer the right connection to the controller for safety-related applications in the form of a fail-safe PLC input. Pre-assembled auxiliary switches reduce the complexity of your structure. The 3RT1 contactors are climate-resistant and approved worldwide (e.g. IEC and UL/CSA).The 3RT contactors with fail-safe control are available in various sizes and in a wide power range. They have a wide AC/DC voltage range and a PLC control input. In the main circuit, the devices can be connected via rails or box terminals.There are a wide range of accessories for these contactors, such as wiring kits that significantly reduce the wiring effort, auxiliary switches or terminal covers.Simple, efficient, always up to date - the SIRIUS modular system.
