Siemens Digital Industry Contactor 3RT2446-1NB30: additional details
Contactor, AC-1, 140 A/690 V/40 °C, S3, 3-pole, AC/DC 20-33 V, with varistor, 1 Normally Closed + 1 Normally Open, frame terminal/screw connection. SIRIUS 3RT24 contactor for switching resistive loads (AC-1). The 3RT24 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 connectivity 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 3RT24 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 both AC and DC actuation in screw connection technology. The comprehensive accessories, such as auxiliary switches, auxiliary relays, etc., are uniform across all sizes. Simple, efficient, always up to date - the SIRIUS modular system.
