Plastic shell refers to the shell of the device using plastic insulator, which is used to isolate the conductor and the grounding metal part. The MCCB usually contains thermomagnetic trip units, while large models of MCCB are equipped with solid state trip sensors. The tripping unit is divided into thermal magnetic release and electronic release. The common rated current includes the following 16, 25, 30, 40, 50, 63, 80, 100, 125, 160, 200, 225, 250, 315, 350, 400, 500, 630A.
