Vacuum contactor, AC-3 500 A, 250 kW / 400 V AC (50-60 Hz) / DC operation 23-26 V UC Auxiliary contacts 2 NO + 2 NC 3-pole, Size S12 Busbar connections Drive: conventional Vacuum contactor SIRIUS 3RT12 for switching motors.The 3RT12 vacuum 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. The vacuum contactors are also characterized by their particularly high switching endurance. They are therefore particularly well suited to frequent switching in jog mode. 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 auxiliary switches 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.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.Simple, efficient and always up to date - SIRIUS modular system.
