Electrical equipment for factories & buildings

Quality components from leading brands, stocked in our own warehouse, with advice from people who install electrical systems every day.

Electrical equipment for factories & buildings

Our showroom and warehouse in Chaloem Phra Kiat, Saraburi stock electrical equipment for factories and buildings: protection devices, control components and cables.

Because we both supply and install, our team can recommend the right parts for the job, whether you install them yourself or have us do it.

Wrongly rated electrical components always cost more than the price difference. A breaker with too low a short-circuit rating, or a contactor chosen on current alone without considering the load type, is a common cause of repeated stoppages that nobody can explain.

Because we both supply components and build panels ourselves, our team sees how each model behaves in service and can check whether what you plan to order is compatible with what is already in your panel — before you buy it.

Worth knowing

What to check before ordering electrical components

Current and voltage ratings match the real duty

Compare against the actual load and duty, not just the model that was there before.

The short-circuit rating (kA) suits your system

Too low a rating is a safety issue, not merely a quality one.

Genuine products with warranty

Components of unknown origin often have questionable real ratings and no valid warranty.

Compatibility with existing panel components

Size, mounting and accessories can differ between models of the same brand.

Delivery lead time

Some items are made to order; confirm the lead time before planning installation.

Space in the existing enclosure

Newer models are not always the same size as the ones they replace.

Getting a quote

What helps us quote components faster

  • Brand, model and rating required
  • A photo of the existing component's name plate
  • Quantity needed and when you need it
  • The load or duty, if you are unsure which model is right
  • Delivery address
  • Company name for the quotation and tax documents
