Component Specifications

Definition
A bridge/jumper is a conductive component designed to electrically connect two or more adjacent terminals within a terminal block assembly. It serves to establish circuit paths, create common connections, or configure terminal blocks for specific wiring schemes. Typically made from metal with insulating covers, it ensures reliable electrical continuity while maintaining safety standards in industrial control panels and electrical distribution systems.
Working Principle
The bridge/jumper operates on the principle of electrical conductivity, providing a low-resistance path between terminals. When installed across adjacent terminals, it creates a continuous electrical connection, allowing current to flow between them. This enables functions like busbar connections, common grounding points, or parallel circuit configurations without requiring individual wire connections for each terminal.
Materials
Copper alloy (typically brass or phosphor bronze) with tin or nickel plating for conductivity and corrosion resistance. Insulating covers are made from polyamide (PA66), polycarbonate (PC), or other flame-retardant thermoplastics rated for industrial temperatures.

Frequently Asked Questions

What is the difference between a bridge and a jumper in terminal blocks?

Bridges typically refer to fixed connections between adjacent terminals, while jumpers are removable or configurable connections. However, the terms are often used interchangeably in industrial contexts.

Can bridge/jumpers be used for different terminal block brands?

No, bridge/jumpers are typically brand-specific due to variations in terminal pitch, dimensions, and locking mechanisms. Always use manufacturer-recommended components.

What safety standards apply to bridge/jumpers?

Key standards include IEC 60947-7-1 for terminal blocks, UL 1059 for terminal connectors, and DIN 46277 for dimensions and performance requirements.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
