The concentrated know-how for high current circuit breakers
MasterPact NT circuit breakers are equipped with MicroLogic control units that offer built-in power and energy metering in addition to basic or advanced protection functions. The MasterPact NT air circuit breaker is the smallest in the world, featuring compact dimensions in one size from 630 to 1600 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 across the entire line. It enables standardization of electrical switchboards by providing peace of mind in terms of choice, installation, and operation.
