What Is a Bus Bar?

A bus bar is a conductive bar—typically made of copper or aluminum—used to distribute electric power across multiple circuits. It acts as a common junction point, allowing multiple wires or components to connect to a single power source. This centralization of power improves efficiency and reduces the mess and complexity of point-to-point wiring.

Benefits of Using Bus Bars in Control Systems

Compact Wiring Layouts: Eliminates tangled wire bundles and supports clean installations
Improved Safety: Reduces hot spots, voltage drops, and loose terminations
Scalability: Easily add or modify connections without rewiring entire panels
Higher Current Handling: Supports heavy loads more efficiently than standard wiring
Durability: Long-lasting materials resist corrosion and heat under industrial conditions

Types of Bus Bars We Offer

Copper Bus Bars – These solid copper bars offer excellent conductivity and are ideal for applications requiring maximum current handling and low resistance.
Insulated Bus Bar Systems – Pre-assembled and finger-safe, these systems are great for compact enclosures and control cabinets where safety and space efficiency are critical.
Flexible Bus Bars – Designed for environments with vibration or tight spaces, these laminated or braided bus bars offer flexibility without sacrificing performance.
Neutral & Ground Bars – Perfect for organizing neutral and ground connections in one place, simplifying wiring and improving clarity in your control systems.
Modular Distribution Blocks – These combine the functionality of bus bars with the convenience of terminal blocks, allowing for fast, clean, and expandable connections.

Mounting Options & Configurations

DIN Rail Mounted – Snaps directly onto standard rails for quick integration
Panel Mounted – Secure attachment to enclosures or backplates
Stackable or Modular Systems – Allows expansion without complete disassembly
Custom Cut Lengths Available – Ask us about trimming to your exact dimensions
