Remarks:

1. If the distance between phases is 150mm, it is necessary to increase the insulated partition between phases;

2. The width of fixed contact is 40mm when the distance between phases is ≤180mm; the width of fixed contact is 60mm when the distance between phases is >180mm;

3. The grounding switch provides output shafts in two directions; the main shaft extends to the left for left operation, and extends to the right for right operation.
