คุณสมบัติเด่นของ ACB SCHNEIDER รุ่น NW
The worldwide benchmark for high current circuit breakers
MasterPact NW circuit breakers are equipped with MicroLogic control units that offer built-in power and energy metering in addition to basic or advanced protection functions. Two sizes are sufficient to cover applications from 800 to 6300 A, with breaking capacity from 42 to 150 kA.
The range comes with a wide choice of standardized accessories. The universal design of the MasterPact circuit breaker line allows most accessories to be used across the entire line. It enables standardization of electrical switchboards by providing peace of mind in terms of choice, installation, and operation.
