AS2.5/3BU is a high-quality 2.5 sq.mm angular multiple connection spring terminal block designed for compact electrical wiring applications in industrial control panels, automation systems, junction boxes, and distribution boards. This terminal block comes in blue color and features 3 connection points, making it ideal for applications where multiple wire connections are required in a limited panel space. It is specially designed to simplify wiring, reduce conductor looping, and improve connection efficiency in electrical systems.
The AS2.5/3BU uses an advanced spring clamp connection system, which ensures secure, vibration-resistant, and maintenance-free electrical connections. Compared to conventional screw-type terminals, spring clamp terminals reduce installation time and provide consistent contact pressure, making them highly suitable for industrial environments with vibration and continuous operation. This feature improves reliability and minimizes the risk of loose wiring over time.
One of the key advantages of this model is its angular wire entry design, which allows wires to enter from the side instead of the top. This helps save conductor length, improves cable routing, and maintains a uniform terminal profile across the panel. Angular terminal blocks are especially useful in compact junction boxes, under-floor wiring systems, and control panels with limited height and space. This makes installation cleaner, more organized, and space-efficient.
The 3-wire multiple connection design eliminates the conventional method of wire looping or cross-connections, simplifying panel wiring and saving additional terminal space. It also supports bridging and shorting links, enabling easy multiplication of electrical connections in control circuits and signal distribution applications. This makes AS2.5/3BU a practical solution for modern electrical panel builders and industrial automation engineers.
Manufactured using durable Polyamide insulated housing, AS2.5/3BU offers excellent electrical insulation, flame resistance, heat resistance, and mechanical durability. It is built for demanding industrial environments where safe, long-lasting, and reliable electrical connections are essential. The terminal block is suitable for DIN rail mounting (DIN 35 / DIN 35-15), ensuring quick installation and compatibility with standard control panel assemblies.
With a rated voltage of 800V and rated current of 24A, AS2.5/3BU provides dependable electrical performance for industrial wiring applications. It supports conductor sizes from 0.34 mm² to 2.5 mm² stranded and up to 4 mm² solid conductors, making it versatile for various industrial and commercial electrical applications. Its compact 5 mm width design helps maximize DIN rail utilization in high-density installations.
