Siemens Contactor

Power contactor, AC-3, 51A, 22kW / 400 V, 4-pole, AC/DC 83-155 V, 50/60 Hz, with integrated varistor, main contacts: 2 normally open + 2 normally closed, auxiliary contacts: 1 normally open + 1 normally closed, screw connection, size: S2. Contactor SIRIUS 3RT25 for polarity switching in hoisting motor applications or for switching two separate loads. The 3RT25 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 load branch. Many of the device combinations are factory-tested. The contactors provide optimal connection to the control system for every application (parallel, via ASi or IO-Link). Integrated auxiliary switches reduce the complexity of your setup. The front connections allow for easy wiring. The 3RT25 contactors are climate-resistant and globally approved (e.g., IEC and UL/CSA). They are available in various sizes and a wide power range for AC and DC operation. In addition to screw connection technology, the devices are also available with spring-loaded terminals for a quick, maintenance-free, and vibration-resistant connection. The comprehensive accessories, such as auxiliary switches, auxiliary relays, etc., are standardized across all sizes. Simple, efficient, always up to date - the SIRIUS modular system.
