Q2431-40 - 40A Circuit Breaker

Q2431-40 - 40A Circuit Breaker

Need to match a Q2431-40 circuit breaker already installed in your equipment? Start with the details that matter. This Type Q24 plug-on circuit breaker is rated at 40 amps and has a 3-pole configuration, with an interrupting rating of 10 kA.I.C. at 240VAC.

One thing worth paying close attention to is the connection. The Q2431-40 has two legs that plug in, while the third leg feeds through. That's a fairly specific arrangement, so it's a detail you'll want to confirm when matching an existing breaker. Physical size matters, too. The unit measures 4.81 inches high, 2.25 inches wide, and 2.5 inches deep.

For older electrical equipment, finding the right breaker isn't simply a matter of matching the amp rating. The type, pole count, voltage, interrupting rating, dimensions, and connection arrangement all need to line up with the application. When your equipment calls for the Q2431-40 and these specifications match, this breaker provides the form, fit, and function needed for the existing system. It's built to last when properly installed, maintained, and used within its specified ratings.
