Malfunction due to transient inrush current
An MCCB may trip if the overcurrent detection device detects
higher than normal transient current, like motor starting
current or transformer exciting inrush current. One way to
prevent this is to select an MCCB with instantaneous tripping
characteristics higher than the motor starting current or
transformer exciting inrush current.
