Schütz AC-1, 60 A, 400 V / 40 °C, 4-pole, AC/DC 175-280 V, 50/60 Hz, with integrated varistor, auxiliary contacts: 1 NO + 1 NC, screw connection, size: S2, special variant: 4th pole: 110 A SIRIUS 3RT23 contactor for switching resistive loads. The 3RT23 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 offer the optimal connection to the control system for every application (parallel, via ASi or IO-Link). Integrated auxiliary contacts reduce the complexity of your setup. The front connections allow for easy wiring. The 3RT23 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 connections for a quick, maintenance-free, and vibration-resistant connection. The comprehensive accessories, such as auxiliary contacts, auxiliary relays, etc., are standardized across all sizes. Simple, efficient, always up to date - the SIRIUS modular system.
