Note
1.The MCCB has L; M; H types according to their rated limit short-circuit breaking capacity.
2.The MCCB is advantageous for its compact body, high breaking capacity(some even on flying arc), short arc-casting.
3.The MCCB has function of insulation wit its mark
4.The product complies with IEC60947-2, GB14048.2. Type code & signification
5.N-P type from 4-P has 3 types: A type: N-P without current tripper(normally open);
6.B type: N-P without current tripper working together with other 3P;
7.C type: N-P without current tripper working together with other 3P;
8.No code for distribution type breakers, 2 for motor-protection type;
9.No-code for distribution type breakers, 2 for motor-protection type;
It can be divided into L (common) type, M (standard) type and H (high) type. L type with connecting current equal to relevant frame level and M type with breaking capacity equaling to their frame level according to their rated limited short short-circuit breaking capacity (l c u).
