ASI-Automation Systems Interconnect NDB2-63C Data Sheet

STANDARD, MCB

UL1077 Recognized
Supplementary Protector

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 offered 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.
