Power contactor, AC-3 185 A, 90 kW / 400 V coil AC 50/60 Hz and DC 200-277 V x (0.8-1.1) F-PLC input 24 V DC 3-pole size S6 auxiliary contacts 2 NO + 2 Oe non-detachable (SUVA) main circuit: rail control and auxiliary circuit: screw connection SIRIUS 3RT1 power contactor for switching high-power motors, specially designed and validated for simple 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 performance combined with a compact design and high contact reliability. They can be combined in many different ways with other components in the load feeder. The contactors offer the right 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, 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 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.
