Product line
Medium-voltage switchgear, ring main units and low-voltage distribution panels — KYN28, HXGN, SF6 RMU, GGD, GCS, GCK and MNS series from 400 V to 33 kV.
Millenium fabricates, wires and tests medium- and low-voltage switchgear on its own sheet-metal and assembly lines. The MV range covers KYN28-type withdrawable vacuum circuit-breaker panels to 12 kV and 24 kV, HXGN fixed panels, SF6 and solid-insulated ring main units to 33 kV, and gas-insulated compact switchgear; the LV range covers GGD fixed, GCS/GCK withdrawable and MNS modular panels for distribution, motor control and power-factor correction from 400 V to 1,000 V.
Assemblies are built to IEC 62271-200 and IEC 61439-1/-2 with the internal-arc classification, busbar rating, protection relays and communication interfaces (Modbus, IEC 61850, DNP3) the project specifies.
No products match that search. Try a rating (e.g. “1600 kVA”), a voltage (“33 kV”) or a type (“ring main unit”) — or describe what you need and we will configure it.
Compare RMUs and metal-clad KYN28 switchgear on IEC 62271-200 classes, fault levels, extensibility, protection and cost.

Read the project sheet →A ring main unit is a compact, sealed switching unit for looped distribution networks with limited protection functions; metal-clad (KYN28-type) switchgear uses withdrawable vacuum circuit breakers in separate compartments for primary distribution with full protection, metering and higher fault ratings.
GGD fixed panels, GCS and GCK withdrawable panels and MNS modular assemblies, built to IEC 61439-1/-2 with ratings to 6,300 A and IP30–IP65 enclosures.
Yes. Panels are supplied with the relays, CTs, VTs and metering specified, and can communicate over Modbus RTU/TCP, IEC 61850 or DNP3.
