Power relay, AC-3 9 A, 4 kW / 400 V 1 Ö, AC 110 V, 50 Hz, 120 V 60 Hz, 3-pole, size S00, screw connection, vertical installation position. SIRIUS 3RT2 power relay for motor control. The 3RT2 relays 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 consumer 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 3RT2 relays are climate-resistant, globally approved (e.g., IEC and UL/CSA), and IE3/IE4 ready. They are available in various sizes and a wide power range with AC and DC actuation. In addition to screw connection technology, the devices are also available with spring-loaded connections for quick, maintenance-free, and vibration-resistant connections. The comprehensive accessories, such as auxiliary contacts, auxiliary releases, etc., are uniform across all sizes. The available connection blocks, function modules, and the SIRIUS 3RV29 power supply system significantly reduce wiring effort. The 3RT2 power relays replace the proven 3RT1 series (up to 55 kW). Simple, efficient, always up to date - the SIRIUS modular system.
