SF6 load break switch(manual type)
EMT's GSS, which is operated electrically through remote controller and manually, is used for load breaking of overhead distribution lines.
This is very compact owing to the introduction of simple extinguishing mechanism ensured by the high insulation and superior interrupting characteristics of SF6 gas.
EMt's GSS has been tested by IEC60265-1, ANSI 37.41, KSC 4509, JIS C 4304 and has acquired the ISO-9001 as International quality system certification
