General

L&R developed its own brand pole mounted vacuum switch with different functions, in order to full fill different clients’ demand.

The vacuum switches are developed base on PVCB type original switch.

Its pursuit of high reliability, easy to maintain design concepts to create a generation of superior product, is the most reliable electric power system the best option.

Different type of expanding switches is optional by client’s requirement.

L&R all series switches meet the following criteria: ANSI/IEEE C37.60/EC 62271-100(GB1984-2003 China standard)GBT1 1022-1999 China Standard, IEC 60255-11, IEC 60255-21-1 Class I, IEC 60255-21-2 Class I, IEC 60255-21-3 Class I, IEC 60255-22-1 Class III, IEC 60255-22-2 Class IV,IEC 60255-22-3 Class III, IEC 60255-22-4 Class IV
