Siemens 3RT1456-2XB46-0LA2

Power contactor AC-1 275 A / 690 V / 40°C, 3-pole, Uc: 24 V DC (0.7-1.25), PLC input 24 - 110 V DC. Drive: electronic, auxiliary contacts 2 S + 2 Ö, main current: rail. Control and auxiliary circuit: spring terminal connection, extended operating conditions railway IEC 60077.

The SIRIUS 3RT14 power contactor is designed for switching resistive loads under extreme conditions, such as 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.

The contactors can be combined in various ways with other components in the load branch and 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 and globally approved (e.g., IEC and UL/CSA). This variant features an extended operating and temperature range for harsher environmental conditions.

They are available in various sizes and a wide range of power ratings. 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 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.
