power contactor, AC-3e/AC-3 185 A, 90 kW / 400 V Uc: 24 V DC x (0.7-1.25) PLC input 24-110 V DC 3-pole, auxiliary contacts 2 NO + 2 NC drive: electronic main circuit: busbar control and auxiliary circuit: spring-loaded terminal extended rated condition railroad IEC 60077 Power contactor SIRIUS 3RT1 for switching motors under extreme conditions, e.g. for railway applications. The 3RT1 contactors are part of the modular SIRIUS system with its optimally coordinated products. They offer convincing performance and high contact reliability despite their compact design. They can be combined with a variety of other components in the load feeder. The contactors offer the best connection to the automation level for every application (direct or via PLC input). Pre-installed auxiliaryswitches reduce the complexity of your design. The 3RT1 contactors are climate-resistant, approved for worldwide use (e.g. IEC and UL/CSA) and are IE3/IE4-ready. This version is characterized by an extended operating and temperature range for tougher ambient conditions. They are available in various sizes and in a wide performance range. They have a DC wide voltage range and a PLC control input. The devices can be connected in the main circuit by means of rails or box terminals. For the auxiliary and control circuit they are also available with spring-loaded terminals for fast, maintenance-free and vibration-proof connection. A wide range of accessories is available for these contactors, such as wiring kits that considerably reduce wiring outlay, auxiliary switches or terminal covers. The 3RT1 power contactors for extreme conditions replace the proven 3TB5 series. Simple, efficient and always up to date - SIRIUS modular system.
