Siemens Vacuum contactor

Vacuum Contactor AC-3e/AC-3 300 A, 160 kW / 400 V, 3-pole, Uc: 21-27.3 V AC (50-60 Hz) / DC SPS input 24 V DC Drive: electronic Auxiliary contacts 2 S + 2 Ö Main circuit: rail Control and auxiliary circuit: screw connection. The SIRIUS 3RT12 vacuum contactors are designed for motor switching. The 3RT12 vacuum contactors are part of the SIRIUS modular system with optimally coordinated products. They impress with high performance while maintaining a compact design and high contact reliability. The vacuum contactors also feature an exceptionally long switching lifespan, making them particularly suitable for frequent switching in momentary operation. They can be combined in various ways with other components in the load branch. The contactors provide the appropriate connection to the control system for every application (directly or via PLC input). Pre-assembled auxiliary switches reduce the complexity of your setup. The 3RT1 contactors are climate-resistant, globally approved (e.g., IEC and UL/CSA), and IE3/IE4 ready. They are available in various sizes and a wide range of power ratings. They feature a DC wide voltage range and a PLC control input. In the main circuit, the devices can be connected via rails or frame terminals. For the auxiliary and control circuit, they are also available with spring-loaded connections for a quick, maintenance-free, and vibration-resistant connection. A wide range of accessories is available for these contactors, such as wiring kits that significantly reduce wiring effort, auxiliary switches, or terminal covers. Simple, efficient, always up to date - the SIRIUS modular system.
