Medium-voltage switchgear receives power from the utility at 11–36 kV and feeds primary distribution transformers, large motors, and MV cable networks. It groups vacuum or SF6 circuit breakers, disconnectors, earthing switches, and protection relays into a single metal-enclosed assembly.

Schneider Electric's MCset, PIX-S, and PremSet ranges cover air-insulated and shielded solid-insulated MV switchgear up to 24 kV with Sepam and Easergy P3 protection.

FAQ

Frequently asked questions

What voltage range does NLC's medium voltage switchgear cover?

It receives power from the utility at 11–36 kV and feeds primary distribution transformers, large motors, and MV cable networks. The panels are offered at voltage levels of 7.2, 12, 17.5, and 24 kV.

What insulation and circuit breaker types are available?

Panels are available air-insulated, gas-insulated, or solid-insulated, with vacuum or SF6 circuit breakers grouped together with disconnectors, earthing switches, and protection relays in a single metal-enclosed assembly.

Which Schneider Electric ranges and protection relays are used?

The switchgear is built with Schneider Electric MCset, PIX-S, PremSet, and GMA ranges, covering air-insulated and shielded solid-insulated MV switchgear up to 24 kV with Sepam and Easergy P3 protection relays.

Does the switchgear have an internal arc classification?

Yes. The switchgear carries internal arc classification IAC-AFLR.

Where is MV switchgear typically used?

Typical applications include utility primary substations, industrial in-plant distribution, large hospitals and university campuses, and airports, ports, and infrastructure projects.

What is the IAC-AFLR internal arc classification?

IAC-AFLR means the metal-enclosed switchgear is tested for internal arc faults with accessibility from the front, lateral, and rear sides, protecting operators in the event of an internal fault.

How do I select between air-insulated, gas-insulated, and solid-insulated panels?

The choice depends on available space, environment, and maintenance preference: solid-insulated and gas-insulated panels are compact and sealed for harsh or tight sites, while air-insulated panels suit conventional substations. Our engineers can advise on the right type for your project.

Is the switchgear type-tested and certified?

As authorised Schneider Electric assemblies, the MCset, PIX-S, PremSet, and GMA ranges are built and type-tested to international IEC standards, with test reports and certifications available on request.
