POLES

1.According to the product poles, it can be divided into two levels: 100A and 225A. There are no four levels in three-pole and four-pole 800.

2. Types of Neutral Pole N Pole in Quadrupole Products. It can be divided into A,B,C,D.

A: N-pole does not install overcurrent tripper, and N-pole is always connected and does not share with other three poles.

B: N pole does not install overcurrent tripper, and N pole is combined with other three poles; N pole is combined first and then divided

C: N-pole is equipped with over-current tripper, and N-pole is combined with other three poles, N-pole is combined first and then divided.

D: The N-pole is equipped with over-current tripper, and the N-pole is always connected, which is not combined with other three poles.
