NA240 - 40Amp Circuit Breaker Description
NA240 - 40Amp Circuit Breaker
Need an NA240 circuit breaker for an existing installation? This new aftermarket breaker is a form-, fit-, and function-replacement for the FPE NA240. It fits the existing breaker location in compatible equipment while maintaining the same basic configuration needed for the application.
The NA240 is a 40-amp, 2-pole thermal magnetic circuit breaker with a Stab-On connection. It carries a 10 kA.I.C. rating at 120/240VAC and measures 3.38 inches high, 2 inches wide, and 2.31 inches deep.
Finding the right replacement breaker isn't just about matching the amperage. The number of poles, voltage rating, connection style, interrupting rating, and physical size must all match the equipment. This NA240 was specially designed with those replacement requirements in mind.
For your compatible electrical equipment that calls for the NA240 configuration, it provides a straightforward way to replace the existing breaker without changing the specified breaker type or electrical ratings. It's built to last and intended specifically for use as a replacement in compatible legacy systems.
