Questions buyers ask

What is the HSN code for an RMU?

85372000. A complete ring main unit is a board for more than 1000 V, so it ships under 85372000 together with MV switchgear panels.

What voltage range does the MV switchgear cover?

11 kV to 33 kV, air-insulated (AIS) or gas-insulated (GIS), with short-time ratings up to 25 kA for 3 seconds.

What is the HSN code for a vacuum circuit breaker?

85352121 for an 11 kV VCB and 85352122 for 33 kV. Breakers fitted inside a panel ship with the panel under 85372000.

Which standards apply to MV switchgear and RMUs?

IEC 62271-100, IEC 62271-200 and IEC 62271-1, with internal arc classification IAC AFLR on request.

Can RMUs be supplied SCADA-ready?

Yes. RMUs and switchboards can be supplied with an RTU, numerical protection relays and motorised operation for remote switching.
