Description

Contactor, AC-3 16 A, 7.5 kW / 400 V 1 S, DC 24-34 V, 0.7-1.25*US with integrated varistor size S00, spring-loaded connection suitable for PLC outputs suspended mounting position SIRIUS 3RT2 contactor for switching motors under extreme conditions, e.g. for railway applications.
The 3RT2 contactors are part of the SIRIUS modular system with its optimally coordinated products. They impress through their high performance while at the same time compact design and high contact reliability. They can be combined with other components in the load feeder in many ways. Many of the device combinations are factory tested. The contactors offer the optimum connection to the controller for each application (parallel, via ASi or IO-Link). Integrated auxiliary switches reduce the complexity of your design. The front connections enable easy wiring. The 3RT2 contactors are climate-proof, approved worldwide (e.g. IEC and UL/CSA) and IE3/IE4ready. This variant is characterized by an extended working and temperature range for harder ambient conditions.
They are available in various sizes and in a large power range in AC and DC operation. In addition to screw connection technology, the devices are also continuously available with spring-type terminals for a fast, maintenance-free and vibration-proof connection.
The comprehensive accessories, such as auxiliary switches, auxiliary releases, etc., are uniform for all sizes. The available connection blocks, function modules and the SIRIUS 3RV29 infeed system considerably reduce the wiring effort.
Simple, efficient, always up-to-date - the SIRIUS modular system.
