AS4/4R is a 4-pole red shorting link / jumper bar accessory specially designed for industrial electrical terminal block systems where common electrical distribution, circuit linking, and visual circuit identification are required. In electrical panels, switchboards, PLC cabinets, and automation systems, multiple terminals often need to share the same electrical input. Instead of using separate jumper wires, the AS4/4R provides a clean and efficient cross-connection solution.
This accessory is used to create a common electrical bridge across four adjacent terminal blocks, allowing one incoming electrical potential to be distributed safely and uniformly across multiple circuits. This reduces manual wiring, improves panel organization, and saves installation time.
Its red color body adds visual identification benefits and is commonly used for warning circuits, emergency control circuits, special phase circuits, or dedicated electrical sections where quick visual recognition is important.
The AS4/4R works as a plug-in shorting link, where the conductive metal bridge connects four adjacent terminal blocks electrically through a single integrated jumper design.
Its working function provides:
The integrated conductive strip ensures reliable electrical continuity across all connected terminals while maintaining a compact and professional panel layout.
The red color coding provides quick visual identification for circuits that require special attention inside electrical panels.
Safety advantages include:
This helps technicians identify critical electrical sections quickly and safely.
Red accessories are commonly used in industrial panels for:
This creates better circuit visibility and organized maintenance access.
The AS4/4R is manufactured using high-conductivity electrical metal with industrial-grade insulated carrier support, designed for long-term industrial panel use.
Construction advantages include:
Its rugged design ensures dependable cross-connection performance.
Using AS4/4R improves electrical panel layout by replacing loose jumper wires with a structured terminal bridge connection.
