塑造了案件的断路器

Main Technical Data & Characteristics: Moulded case circuit breaker DZ20,its rated Insulated voltage is 660V,applied to AC50Hz,rated work voltage 380(400)v or below,rated current is from 16A to 1250A. It is generally used to distribute power,but Y,J and G type 225A and Y type 400A also can be used to protect motor.Under normal condition,circuit breaker is to unfrequently switch over of line and unfrequently starting of motor.
