Siemens SIRIUS 3RT7916-2PR11 Auxiliary Contact Block 1NO+1NC, S00 Size Original Brand New

Overview

The Siemens SIRIUS 3RT7916-2PR11 is an essential auxiliary contact block designed for use with the Siemens SIRIUS 3RT7 contactor series. This versatile component provides a reliable 1 normally open (1NO) and 1 normally closed (1NC) contact configuration, perfect for a wide range of control and signaling applications in industrial automation. Its compact S00 size makes it an ideal fit for space-constrained panels and equipment, ensuring seamless integration and high performance.

Key Benefit

• Enhanced Reliability: The 1NO+1NC configuration provides reliable feedback and control signaling for your systems, improving operational safety and efficiency.
• Seamless Integration: Designed specifically for the SIRIUS 3RT7 contactor family, this auxiliary contact block ensures a perfect mechanical and electrical fit, simplifying installation and maintenance.
• Space-Saving Design: The compact S00 size allows for high-density mounting in control cabinets, maximizing available space without compromising functionality.
• Durable and Long-Lasting: Built with high-quality materials, the 3RT7916-2PR11 is engineered to withstand demanding industrial environments, offering long-term reliability and reducing downtime.

Functionality

The 3RT7916-2PR11 auxiliary contact block snaps easily onto the front of a compatible SIRIUS 3RT7 contactor. It functions by providing additional switching contacts that operate in tandem with the main contactor. The 1NO contact closes when the contactor is energized, while the 1NC contact opens, allowing for the creation of intricate control circuits, interlocking systems, and status indicators. This dual functionality is crucial for safety circuits, motor feedback loops, and automated sequences.
