Product Description
The 7TB712.91 is a B&R Automation terminal block designed for reliable and efficient electrical connections in automation systems. With its robust construction and high-quality materials, this terminal block ensures secure and durable connections for power and signal distribution. It is a cage clamp terminal block variant, which allows for easy and secure connection of wires without the need for additional tools. The cage clamp design also enhances electrical contact stability, improving overall system reliability. This terminal block features a 12-pin configuration, providing multiple connection points for power and signal distribution. This allows for flexible and organized wiring in automation systems.
The 7TB712.91 is designed to support only copper wires, ensuring compatibility with standard wiring types used in automation systems. This restriction prevents issues related to aluminum-copper connections, which can lead to corrosion and decreased conductivity. The terminal block comes with a 3.5 mm pitch, providing a compact design that allows for efficient use of space in control systems and automation panels. This smaller pitch size facilitates higher density wiring, making it suitable for applications where space is limited. It has a rated nominal voltage rating of 300 V, ensuring safe and reliable operation in various industrial systems. This high-voltage rating supports demanding applications, providing stable and consistent power transmission.
The 7TB712.91 maintains a contact resistance of ≤4.2 mΩ, ensuring low electrical resistance and efficient current transfer between connected components. This feature reduces energy loss, enhances conductivity, and improves overall system performance. This unit is built to support a connection cross section of 26 to 14 AWG, which allows it to efficiently accommodate a wide range of wire sizes. This versatility allows users to utilize various cable types, ensuring greater flexibility in wiring configurations.
