Busbar terminals

Overview

Busbar Terminals are key components in power distribution systems,
which realize centralized transmission and distribution of large currents through highly conductive busbars. They are designed for industrial control cabinets, data centers, large electrical equipment and new energy systems to ensure efficient, safe and reliable power supply.

Key advantages

High conductivity

Made of high-quality copper or aluminum alloy materials to ensure low-resistance and low-loss power transmission.

High current carrying capacity

Supports currents from tens of amperes to thousands of amperes to meet power distribution needs of various sizes.

Compact structure

Modular design saves space and is easy to install and maintain.

Safe and reliable

With short-circuit protection, overload protection and grounding functions to ensure stable operation of the system.

Flexible expansion

The number of busbar terminals can be easily increased or decreased according to actual needs to adapt to future expansion needs.

Basic knowledge

Busbar material selection: Copper busbar has excellent conductivity, but the cost is high; aluminum busbar is cost-effective, but the conductivity is slightly inferior.

Current carrying capacity calculation: It is necessary to consider factors such as busbar cross-sectional area, material, ambient temperature, and heat dissipation conditions.

Installation and maintenance: Busbar terminals must be firmly installed to avoid loosening; check the connection points regularly to ensure that there is no overheating or corrosion.

Frequently asked questions

Q1: What are the advantages of busbar terminals compared to cables?

A: Busbar terminals have higher current carrying capacity, lower loss and better heat dissipation performance, and are suitable for large current and long-distance power transmission.

Q2: How to choose the right busbar terminal material?

A: According to the current demand, cost budget and space constraints of the application, comprehensively consider the choice of copper or aluminum material.

Q3: What matters need to be paid attention to when installing busbar terminals?

A: Ensure that the busbar terminals are firmly installed and the connection points are in good contact; follow the manufacturer’s installation guidelines to avoid damage caused by over-tightening.

Selection & support

Selecting LEIPOLE busbar terminals

Match the busbar profile, cable size and current before confirming a terminal.

Which busbar terminals does LEIPOLE supply?

SU 201 to SU 300 terminals clamp cables of 1 to 185 mm² onto 4–5 mm or 9–10 mm thick busbars. LP conductor terminals carry 180 to 440 A for 1.5 to 120 mm² cables, and ProfiClip and PowerClip brace terminals carry 500 to 1600 A, or 2000 A with centre feed, on flat bars and double-T and triple-T sections.

Check technical documents

How do I choose a busbar terminal?

Match the busbar thickness or profile (4–5 mm, 9–10 mm, double-T or triple-T), the cable cross-section to be clamped and the maximum current. Tighten to the torque in the model table, from 2 Nm for SU 201 to 12–15 Nm for SU 205 and SU 300, and check the connections for overheating at service intervals.
