A circuit breakers ability to protect its down stream equipment is predicted on its ability to understand and react to its electrical environmental conditions. IE it needs a good brain:

The NB Pro micro procession based tripping system provides the finest protection in an extremely rugged, user friendly package. The NB pro comes one way – loaded. The only options being communications and voltage monitoring (with voltage comes power as well).

Now one trip kit fits all of your breakers. The same kit that you use on GE will work on Westly house, ITE, Federal Pacific and more. Weather 600A or 400A- it’s the same NB Pro.

The NB Pro needs no rating plugs. The LCD ARAD out is standard. Plain English programming is standard. A built in Ammeter is standard. Short time is standard. Plain English programming is standard. Ground fault is standard. Analytical trip information such as which phase faulted, on what trip characteristic and on what value of current is standard.
