Yes. Our MNS series low voltage switchgear follows the standard modular dimensions and structural design (E=25mm). The drawers, incoming/outgoing units, and busbar structures are fully compatible and interchangeable with standard market MNS configurations, making it ideal for system expansions or cost-effective project retrofits.
Every shipment includes: IEC 61439-2 type-test certificate from an accredited lab, factory routine test report, material certificates for copper busbar and steel, component certificates for breakers and relays, CE declaration of conformity, and destination-country certificates (SASO, SNI, GOST) if requested. A type-tested IEC 61439 assembly is only as credible as the paperwork that comes with it.
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.
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.
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.
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.
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.
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.
