Schütz AC-1, 40 A, 400 V / 40 °C, 4-pole, AC 110 V, 50 Hz / 120 V, auxiliary contacts: 1 S + 1 Ö, screw connection, size: S0. The SIRIUS 3RT23 relay is designed for switching weak or non-inductive loads. The 3RT23 relays are part of the SIRIUS modular system with optimally coordinated products. They impress with high performance in 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 relays provide 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 relays 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 in the smaller sizes are also consistently available with spring-loaded terminals for a quick, maintenance-free, and vibration-resistant connection. The comprehensive accessories, such as auxiliary contacts, auxiliary relays, etc., are standardized for all sizes. Simple, efficient, always up to date - the SIRIUS modular system.
