Q2431-50 - 50A Circuit Breaker

Q2431-50 - 50A Circuit Breaker

When you're replacing a breaker in an existing electrical system, getting the details right matters. The Q2431-50 is a Type Q24, 3-pole, 50-amp circuit breaker rated at 10k AIC at 240VAC. It uses a specific connection setup, with two legs that plug in and a third leg that feeds through. That configuration is an important detail when you're trying to match a breaker already installed in older or legacy equipment.

The Q2431-50 measures 4.81 inches high, 2.25 inches wide, and 2.5 inches deep. It's intended for applications that require this particular Q24 design, rather than any 50-amp, 3-pole breaker. For electricians, maintenance crews, and facility managers, checking the part number, dimensions, electrical ratings, and connection style is especially important. When properly matched to compatible equipment and used within its specified ratings, this breaker is built to last and provides the form, fit, and function needed to keep an existing system in service.
