Description
Siemens 3RT20353XB440LA2
railway contactor, AC-3 40 A, 18.5 kW / 400 V 2 NO + 2 NC DC 24 V, 0.7-1.25* US, with varistor , 3-pole, size S2, spring terminal SIRIUS 3RT2 contactor for controlling motors under extreme conditions, e.g. for railway applications.\nThe 3RT2 contactors are an integral part of the SIRIUS modular system with its products perfectly matched to each other. They convince with great power in a compact design and high contact reliability. They can be combined in various ways with other components in the starter. Many of the device combinations are already tested at the factory. The contactors offer the optimal connection to the controller for every application (parallel, via AS-i or IO-Link). Integrated auxiliary switch blocks reduce mounting complexity. Front connections simplify simple wiring. The 3RT2 contactors are tropicalised, worldwide approved (e.g. IEC and UL/CSA) and IE3/IE4ready. This variant is characterized by an extended working and temperature range for harsh environmental conditions.\nThey are available in different construction sizes and in a wide power range for AC and DC control. The devices are available not only with screw terminals but also with spring-loaded terminals for quick, maintenance-free and vibration-resistant connection.\nAll accessories such as e.g. the auxiliary contact blocks, the auxiliary releases etc. they are uniformly suitable for all construction sizes. The available connection modules, function modules and the SIRIUS 3RV29 power supply system significantly reduce the cabling effort.\nSimple, efficient, always up-to-date - the SIRIUS modular system.
