AS4BK is a shorting link / jumper bar accessory in black color specially designed for industrial electrical terminal block systems where common electrical potential distribution, circuit bridging, and organized cross-connection wiring are required. In electrical control panels, PLC cabinets, switchboards, automation systems, and machine control assemblies, several adjacent terminal blocks often need to share a common electrical supply or signal distribution.
Instead of using separate jumper wires for each connection, the AS4BK provides a compact plug-in cross-connection solution that electrically bridges adjacent terminal blocks, creating a common distribution path. This reduces manual wiring, improves panel organization, and makes electrical assemblies cleaner and more maintenance-friendly.
The black body color also helps in dedicated circuit grouping, neutral visual differentiation, or specific wiring section identification in industrial control systems.
The AS4BK works as a plug-in shorting link / jumper accessory, inserted directly into compatible terminal blocks to create a common electrical bridge.
Its working design provides:
The conductive internal strip transfers electrical continuity across connected terminals, allowing multiple terminals to share the same electrical feed safely and efficiently.
This creates a compact and professional terminal block cross-connection system.
The black color coding helps in dedicated wiring section recognition and circuit grouping.
Safety advantages include:
This helps technicians identify grouped circuits quickly during maintenance.
Black accessories are commonly used for:
This improves structured electrical panel layout.
The AS4BK is manufactured using high-conductivity electrical metal with industrial-grade insulated carrier support, designed for industrial electrical applications.
Construction advantages include:
Its robust design ensures dependable terminal cross-connection performance.
Using AS4BK improves electrical panel layout by replacing loose jumper wires with a structured terminal bridging system.
