AS4/3BU is a 3-pole shorting link / jumper bar accessory in blue color, designed for terminal block cross-connection in industrial electrical panels, switchboards, automation systems, PLC panels, and control panels. This accessory is used to create a common electrical connection between adjacent terminal blocks, allowing one supply to be distributed across multiple terminals safely and efficiently.
The AS4/3BU shorting link simplifies panel wiring by eliminating the need for individual jumper wires between terminal blocks. Instead of using separate conductors, this accessory creates a neat and organized commoning arrangement, reducing wiring complexity and improving electrical panel aesthetics. It also helps reduce installation time and improves maintenance accessibility in industrial electrical systems.
The blue color coding makes this jumper bar suitable for circuit identification, neutral circuit distribution, or specific terminal group separation in electrical panels. Color-coded accessories help electricians and maintenance engineers quickly identify circuit sections during installation, fault finding, and servicing.
Manufactured from high-conductivity metal with durable insulated support material, AS4/3BU provides dependable electrical continuity, high mechanical strength, and long service life in industrial operating conditions. Its compact design allows easy plug-in installation into compatible terminal blocks without affecting surrounding wiring.
Because of its precision engineering, reliable cross-connection performance, and organized panel wiring benefits, the AS4/3BU is widely used in automation panels, switchgear assemblies, distribution boards, machine control systems, OEM electrical panels, and industrial wiring applications.
