10.2 SION

Note
SION is indoor used VCB with 3 poles, rated voltage ranging from 7.2 kV to 12kV
circuit-breaker SION is basic configuration, all types past the type test according to IEC standard. For the additional
equipment and part, for example: the parts for connecting to panel, if need to quickly move, shall not withstand
excessive strength. Assure enough distance between interlock and quickly moving part, and living parts. If the costume
wants additional functional parts for VCB, please consult our company, because we have the reliable solutions.
