Siemens 3RT1056-2XB46-0LA2

Power contactor, AC-3e/AC-3 185 A, 90 kW / 400 V Uc: DC 24 V x (0.7-1.25) PLC input 24-110 V DC 3-pole, auxiliary contacts 2 S + 2 Ö Drive: electronic Main circuit: rail Control and auxiliary circuit: spring terminal connection extended operating conditions railway IEC 60077 Power contactor SIRIUS 3RT1 for switching motors under extreme conditions, e.g., for railway applications. The 3RT1 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. They can be combined in various ways with other components in the consumer branch. The contactors provide the appropriate connection to the control system for each application (directly or via PLC input). Pre-assembled auxiliary contacts reduce the complexity of your setup. The 3RT1 contactors are climate-resistant, globally approved (e.g., IEC and UL/CSA), and IE3/IE4 ready. This variant features an extended operating and temperature range for harsher environmental conditions. They are available in various sizes and a wide power range. They have 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 terminal connections for a quick, maintenance-free, and vibration-resistant connection. There is a wide range of accessories for these contactors, such as wiring kits that significantly reduce wiring effort, auxiliary contacts, or terminal covers. The 3RT1 power contactors for extreme conditions replace the proven series 3TB5. Simple, efficient, always up to date - the SIRIUS modular system.
