Power contactor, AC-3e/AC-3 225 A, 110 kW / 400 V AC (50-60 Hz) / DC 200-277 V x (0.8-1.1) F-PLC input 24 V DC 3-pole, auxiliary contacts 2 NO + 2 NC non-detachable Drive: electronic Main circuit: rail Control and auxiliary circuit: screw connection SIRIUS 3RT1 power contactor for switching high-power motors, 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 their high power combined with a compact design and high contact reliability. They can be combined in a variety of 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 setup. The 3RT1 contactors are climate-resistant, approved worldwide (e.g. IEC and UL/CSA) and IE3/IE4ready.The 3RT contactors with fail-safe control are available in various sizes and in a wide performance 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.
