General:
  MG2 is base on the modularization to design and has 125A-1600A 11 different type.It has 3 poles and 4 poles(3 poles+can connection and disconnection neutral pole).It suits for connection and disconnection of the circuit,or electric isolating.It can only electric isolating over 1000A.On the surface,there is no indication the connection and disconnection state mark.
1,It can supply the back window  to see the state of connection and disconnection
2,If you need,and the stype details,you can see the MG2-125A-1600A/H back cabinet load-isolating switch.
