STM2-63N Series is applicable to a line of AC 50Hz/60Hz, 230V in
single pole, 400V in double, three,four poles for protecting
overload and short circuit, and rated current up to 63A. It can
also beused for infrequent line conversion under the normal
condition. The breaker is applicable tolighting distribution system
in industrial enterprise, commercially district, high-rise building
anddwelling house. It conforms with the standards of IEC60898. Specifications | | Standard | | IEC/EN 60898-1 | Electrical
