Basic knowledge

What is Busbar Holder?

It is a very important equipment used to fix and support busbars to avoid that the busbars will loosen or wander despite vibration or temperature changes, Busbar Holders are used.

What to consider when selecting a suitable Busbar Holder

● Busbar sizing – the busbar holder is compatible with 5mm and 10mm busbar

● Load capability – should be able to handle high power systems like mega fuse busbar

● Flexible Protection level (humidity, vibration, high temperature, etc.)

Frequently asked questions

Q1: What are the compatibility of Busbar Holders to Busbars of various sizes?

A: Yes, our products are well applied for the 6-way fuse block with bus bar, 12-way fuse block with bus bar and other specifications.

Q2: Are these brackets for outside?

A: Yes, our busbar holders are made of weather-resistant materials suitable for outdoor environments such as industry, rail transit and EV charging pile.

Why use DIN rail mounted busbar holders in control panels?

They simplify installation and improve layout flexibility, allowing secure busbar mounting without drilling or panel modification.

Are insulated busbar holders necessary for electrical cabinets?

Yes, they reduce the risk of short circuits and improve operator safety, especially in compact or high-voltage enclosures.

What size busbar holders are suitable for 30x10mm copper bars?

Look for holders rated for at least 800A, designed with groove profiles matching the 30x10mm dimension for firm support and insulation clearance.

Can heat resistant busbar holders be used in high-temperature zones?

Absolutely. Use materials like polyamide or glass-filled nylon that withstand up to 120°C or higher without deformation.

How do compact busbar holders benefit control cabinet design?

They save valuable space, allow tighter layouts, and are ideal for modular electrical systems where space efficiency matters.
