ZYM1E series electronic plastic shell circuit breakers (hereinafter referred to as circuit breakers) are suitable for infrequent switching and infrequent starting of motors in circuits with AC 50Hz (or 60Hz), rated insulation voltage of 800V, rated working voltage of 690V and below, and rated working current up to 800A. The circuit breaker has overload long delay inverse time limit, short circuit short delay inverse time limit, short circuit short delay fixed time limit short circuit instantaneous and undervoltage protection functions, as well as residual current protection (optional) and phase loss protection function (optional), which can protect the line and power equipment from damage. The circuit breaker has complete and accurate protection characteristics, which can improve power supply reliability and avoid unnecessary power outages. The "Z, B" type control has a communication interface and can be "four remote" to meet the requirements of the control center and automation system.Circuit breakers are classified into two types based on their rated limit short-circuit breaking capacity: M-type (higher breaking type) and H-type (high breaking type). This circuit breaker has the characteristics of small volume, high breaking capacity, short arc and anti vibration.
