MCCB -  Zhejiang YADE Electric Co. Ltd. professional supply.
Molded case circuit breaker: YDZ20 series of plastic case type circuit breaker, the rated insulation voltage 660V, AC 50Hz, rated voltage is 380V, the rated current of from 16A to 1250. In general as a distribution with, where y, J, G type rated current 225A and below and shell frame as 400Y type molded case circuit breaker can be used as a motor protection. Under normal circumstances, circuit breaker shell as the line without frequent conversion and motor is not frequent starting with.
Four levels of molded case circuit breaker is mainly used for AC 50Hz, below the rated voltage 380V, rated current 16A to 630A three-phase four wire system of the system, it can ensure users and power completely broken open to ensure safety, so as to solve three molded case circuit breaker can not overcome the neutral current is not zero shortcomings. Distribution in molded case circuit breaker, in the distribution network for distribution of electrical energy, and as a circuit and power supply device of overload and short circuit protection.
Motor protection with moulded case circuit breaker in the distribution network as a squirrel cage motor starting and running off as well as the motor overload and short circuit protection. In the series, the rated current of the shell frame is also provided with a transparent cover from the three grade product of 100A-630A, the customer may observe the operation of the product at any time.
