Where It Works Best
The NA40 40 amp breaker is intended for compatible electrical equipment that calls for an NA-style, single-pole, stab-on breaker with a 40A rating, 120VAC voltage rating, and 10k AIC.
It's especially suited to maintenance and replacement work on legacy systems where keeping the existing breaker configuration matters. Rather than changing the application, this breaker provides the required form, fit, and function for an existing NA40 location.
Always match the part number and electrical specifications to the equipment before installation. Confirm dimensions, amperage, voltage, AIC rating, pole count, and connection type.
