Siemens 3RT2045-3XF44-0LA2 Conductor 2 makers, 2 breakers 82 kW 1000 V 77 A + varistor Compatible with (relay brand): Si

Rail contactor, AC-3e/AC-3, 80 A, 37 kW / 400 V, 3-pole, 110 V DC, 0.7-1.25* US, electronic drive, with integrated varistor, auxiliary contacts: 2 S + 2 NC, main circuit: screw connection, control and auxiliary circuit: spring connection, auxiliary switch can be released SIRIUS 3RT2 power contactors for switching motors under extreme conditions, such as for railway applications.
The 3RT2 contactors are part of the SIRIUS modular system with their optimally coordinated products. They convince by high power with a compact design and high contact reliability. They can be combined in a variety of ways with other components in the load feeder. Many of the device combinations have been tested at the factory. The contactors provide optimum connection to the controller (parallel, via ASi or IO-Link) for each application. Integrated auxiliary switches reduce the complexity of your setup. The front connections allow simple wiring. The 3RT2 contactors are climate-proof, worldwide approved (e.g. IEC and UL/CSA) and IE3/IE4ready. This variant is characterized by an extended operating and temperature range for harder ambient conditions.
They are available in various sizes and in a wide power range with AC and DC actuation. Apart from screw connection technology, the devices are also available continuously with spring connection for a fast, maintenance-free and vibration-proof connection.
The comprehensive accessories, such as auxiliary switch, auxiliary release, etc. are uniform for all sizes. The available connection modules, function modules and the SIRIUS 3RV29 infeed system considerably reduce the wiring effort.
Simple, efficient, always up-to-date - the SIRIUS modular system.
