  • Q Can one factory supply my entire IEC 61439 LV switchgear package?

    A

    Yes. A factory building the full IEC 61439 lineup — switchgear, MCC, ATS, APFC, VFD — is more efficient than splitting your order. Busbar fabrication, enclosure welding, testing all follow one ISO 9001 system. Short-circuit coordination covers every panel. Test reports ship as one package. One project manager. One schedule. Standard packages ship in 4 to 10 weeks.

  • Q What is an apfc panel and capacitor bank, and do I need both?

    A

    An apfc panel monitors reactive power and switches capacitor banks to maintain target power factor — typically 0.95. A capacitor bank is the physical set of capacitors inside the APFC panel. You buy them together for industrial facilities with motor loads above 200kW. The APFC panel eliminates utility power factor penalties. Add detuned reactors if your site has significant harmonic distortion from VFDs.

  • Q When do I need an ats panel and vfd panel in my IEC 61439 lineup?

    A

    An ats panel automatically switches to backup power when the grid fails. A vfd panel controls motor speed to reduce inrush current and save energy. You need both where power continuity and motor control matter — hospitals, data centers, industrial plants. The ats panel keeps critical loads running. The vfd panel manages fans and pumps. Both sit side by side in the same electrical room.

  • Q What is a motor control center and how does it differ from a power distribution board?

    A

    A motor control center groups starters, contactors, and overload relays for motor control. A power distribution board distributes power to lighting, receptacles, and small equipment. The motor control center handles dynamic motor inrush loads. The power distribution board handles steady-state static loads. Most buildings need both, and sourcing from one IEC 61439 supplier gives you coordinated protection and one set of test documents.

  • Q What is the difference between switchgear vs switchboard?

    A

    The switchgear vs switchboard question comes down to testing rigor. Switchgear is type-tested per IEC 61439-2 at an accredited lab. Low voltage switchboards are typically design-verified per IEC 61439-3 with lighter fault ratings and fewer compartments. Switchgear handles 65kA to 100kA. Switchboards max out around 50kA. For main distribution, switchgear is the right choice.

  • Q What is IEC 61439 low voltage switchgear and what does the standard cover?

    A

    IEC 61439 low voltage switchgear is the international standard for type-tested assemblies covering main distribution panels, MCCs, ATS, and APFC. Every lv switchgear unit we build passes short-circuit, temperature rise, and dielectric tests at an accredited lab. The standard covers everything from 400A distribution boards to 6300A main switchgear — all with documented, verifiable performance. You get the certificates with your order.

  • Q What IP rating does your GGD switchgear enclosure have?

    A

    IP54 as standard — dust-tight and moisture-resistant. Works in factories, outdoors, and coastal environments. Powder-coated steel enclosure. No special upgrade required for harsh conditions. Need higher? We can configure for IP65 with gasketed doors and sealed cable entries.

  • Q Do you offer OEM branding on fixed switchgear?

    A

    Yes. Your logo, your color scheme, your nameplate. Multi-language documentation. NDA available if needed. One dedicated project manager handles everything from design review to pre-shipment inspection. No relay race between departments — just one person who knows your project.

We will work with other excellent partners to deliver more high-quality products to the world.
