Cross-connectors for terminal blocks, also known as jumper bars, shorting links, or bridging connectors, are essential components in electrical distribution and control panels. These devices are designed to electrically interconnect adjacent terminal blocks, creating common potential points without the need for additional wiring. Typically manufactured from tinned copper or brass with high conductivity, cross-connectors are available in various pole configurations (2P, 3P, 4P, up to 10P or more) and current ratings ranging from 20A to 200A, depending on the terminal block series. They are compatible with screw, spring-cage, or push-in connection technologies and are often color-coded (e.g., red for phase, blue for neutral, yellow/green for earth) to simplify identification and reduce installation errors. The mechanical design ensures secure locking into the terminal block slots, providing reliable electrical continuity and vibration resistance in industrial environments.

Cross-connectors are widely used in industrial automation, power distribution, building management systems, and process control applications. They are installed in terminal blocks within control cabinets, junction boxes, motor control centers (MCCs), and programmable logic controller (PLC) panels. Common sectors include manufacturing, energy, water treatment, transportation, and commercial buildings. These connectors facilitate the efficient distribution of power, signals, and data across multiple circuits, reducing wiring complexity and improving system maintainability. They are particularly valuable in applications requiring commoning of neutral, earth, or control voltage lines, such as in three-phase power supplies, sensor arrays, or actuator groups.

Our catalog includes a comprehensive range of cross-connectors for various terminal block families, such as the UK series (e.g., UK-5N, UK-10N), ST series (e.g., ST-2.5, ST-4), and SAK series (e.g., SAK-2.5, SAK-4). The article codes typically follow a pattern like "CROSS-UK-5N-4P" or "JMP-ST-2.5-10P", where the prefix indicates the terminal block series, the middle part specifies the current rating or wire size, and the suffix denotes the number of poles. For example, "CROSS-UK-10N-3P" is a 3-pole cross-connector for UK-10N terminal blocks rated at 10A. We also offer custom lengths and pre-assembled kits for specific panel layouts.

Partnering with Electric Automation Network ensures access to genuine, high-quality cross-connectors with real-time pricing and stock availability. Our engineering team provides technical support for selection, compatibility, and installation, including guidance on current derating and voltage drop calculations. We offer express worldwide shipping, ensuring your critical components arrive on time for project deadlines. Whether you need standard jumper bars or specialized bridging solutions, our multilingual portal simplifies procurement across global markets.
