The Siemens 3RV29011D Transverse Auxiliary Switch is a precision-engineered accessory designed for seamless integration with the Siemens SIRIUS 3RV2 motor protection circuit breakers. Built for reliability and ease of use, this 1CO (changeover) switch enhances monitoring and control functionality within your automation setup. Designed to mount transversely on the breaker, it provides clear, consistent feedback signals that help optimize system performance and minimize downtime.
Constructed to meet Siemens' rigorous quality standards, the 3RV29011D ensures dependable performance even in demanding industrial environments. Its screw terminal connections provide a secure, vibration-resistant fit, while the compact form factor saves valuable panel space. Whether used in motor control centers, switchboards, or automation panels, this auxiliary switch is engineered for long-term reliability and low maintenance.
As part of the SIRIUS Control Products line, the 3RV29011D fits seamlessly into Siemens' modular ecosystem. It allows flexible configuration for your circuit protection and control schemes—perfect for expanding or modifying existing setups. It's a one-changeover contact (1CO) that supports both open- and closed-circuit monitoring, giving operators accurate status feedback for operational safety and diagnostics.
Installation is fast and straightforward. The transverse design enables quick mounting onto compatible 3RV2 motor protection switches (sizes S00 to S3) without additional wiring complexity. The screw terminals ensure strong electrical connections, reducing the chance of signal loss or interruption. This makes it ideal for industrial automation, manufacturing lines, and control cabinets where space, reliability, and precision matter most.
A 2-year MRO Electric warranty and ships free with immediate availability for each Siemens 3RV29011D. That means you can count on both performance and convenience. As with all Siemens control components, this auxiliary switch meets global safety standards (UL, CE, RoHS) for consistent, code-compliant installations worldwide.
