Electrical control panel design, fabrication & installation
A panel that is engineered right from the start keeps your machines running safely and is easy to maintain. Our engineers design, build and install control panels around each factory's production process.
E.S. Service and Supply has designed and installed electrical panels for industrial plants for more than 20 years, from small motor control panels to large main distribution boards. Every project starts with a site survey and a real load calculation, so breakers, busbars and protection devices are sized correctly: no over-spending, and no compromise on safety.
Every panel is assembled in our own workshop in Saraburi by experienced technicians, designed to IEC 61439 guidance and checked by a licensed professional electrical engineer. Each panel is function-tested before it is delivered.

Frequently asked questions
Which areas do you serve?
Our office and workshop are in Chaloem Phra Kiat, Saraburi. We serve industrial plants across Thailand. Contact us to discuss your location.
What information do you need for a quotation?
A single-line diagram, a list of machines or loads, and site photos help us quote quickly and accurately. If you don't have drawings yet, our engineers can survey the site and design the system for you.
Which standard do your panels follow?
We design and assemble panels following IEC 61439 for low-voltage switchgear and controlgear assemblies, under the supervision of a licensed professional engineer.
Do you modify or upgrade existing panels?
Yes. We add circuits, replace worn components and upgrade existing panels for new machinery, after an engineer has inspected the panel and the existing system.
Planning an electrical or control panel project?
Send us your drawings or project details. Our engineers will review them and come back with recommendations and a quotation.
