Why making capacity is more than breaking capacity in circuit breakers and contactors?In: Engineering |
[Edit] |
[Edit] 
Making capacity is the max fault current it can carry during closing of breaker, e.g. You are closing a breaker on fault. The making capacity is always higher because it is expressed in peak value not rms, and also because of the DC offset, voltage and PF while closing
