FBI10-5 10PCS Fixed Bridge Jumper for UK3N UKK3 MBKKB2.5 Terminals

These central jumper strips (also known as short‑circuit bars, cross‑connecting links) are matching accessories for DIN‑rail terminal blocks such as UK‑series and SAK‑series terminals. They are made of high‑quality tinned‑copper metal (the fork‑type version has insulating PA plastic carriers). They plug directly into the central slots of terminal blocks to realize parallel connection of multiple adjacent terminal positions, shorten wiring time, standardize circuit distribution inside control cabinets, and replace messy loose jump wires. They are widely applied in electrical control cabinets, automation panels, power distribution boxes and industrial wiring systems.

• Excellent Electrical Conductivity: The main body adopts high‑purity copper with tin‑plated surface. It features low contact resistance, stable current transmission and effectively prevents oxidation for long‑term safe power‑carrying performance.
• Precise Standardized Dimensions: Produced strictly following industry‑standard pitch sizes. The pins match perfectly with the internal structure of compatible terminal blocks for tight plug‑in without wobble or poor contact.
• Robust & Durable Structure: The metal part has high structural rigidity to resist deformation during installation. The plastic‑topped jumper owns high‑temperature‑resistant insulating nylon, which avoids short‑circuit risks between circuits.
• Fast and Convenient Installation: Just insert the metal pins into the terminal block central holes directly without extra tools. It greatly reduces manual wiring work and improves assembly efficiency.
• Wide Compatibility & Flexible Selection: Multiple‑pole options (2‑pin to 10‑pin) are available. Cylindrical‑pin type fits UK3N, MBKKB2.5 terminals and fork‑pin type is for regular feed‑through terminals, meeting diverse circuit‑parallel requirements.
