Terminal connection ability: Bus-bar roe thickness 0.8-2mm
Shell width: Grade Two 35mm
                   Grade Four 70mm

Main Properties:
Except from special indication,grade two switch is two modulus in width;
grade four seitch(3P+N) is four modulus in width
two-side double-functional connection terminals
it is able to connect bus-bar row and single-core wire synchronously
with contact state indicator
various leakage action current specifications
selective protection can be realized easily
It is able to prevent form false action caused by the initial operation of electronic equipment
Action function has nothing to do with main circuit voltage and it is suitable for leakage protection and additional protection.
