The NDB2 series of miniature circuit breakers are UL1077. Recognized for use in circuits where supplementary protection is allowed and required. At only 18mm wide the NDB2 MCB’s can be used in most applications and are an ideal drop-in replacement to existing circuit breakers. The robust design of the NDB2 features a 10kA interrupt capacity which exceeds that o ered by other manufacturers by as much as double the capacity. To insure quality and long-term reliability all NDB2 circuit breakers are tested 3 times at 100% before ever leaving the factory.
