Q2431-30 - 30A Circuit Breaker

Q2431-30 - 30A Circuit Breaker

When you’re replacing a breaker in an existing electrical system, the small details can make all the difference. The Q2431-30 Type Q24 circuit breaker is a 3-pole, 30-amp breaker rated at 10 kA I.C. at 240 VAC. It uses a less-common connection arrangement that’s important to note: two legs plug in, while the third leg feeds through. That makes the Q2431-30 especially relevant for maintenance and replacement work where the existing equipment was designed around this exact configuration. The breaker measures 4.81 inches high, 2.25 inches wide, and 2.5 inches deep. If you’re trying to match an existing Q2431-30, check more than just the amperage. The Type Q24 designation, three-pole layout, voltage and A.I.C. ratings, dimensions, and plug-on/feed-through configuration should all comply with the equipment requirements. For compatible legacy systems, it offers a straightforward way to maintain the original form, fit, and function. Simply put, this is a breaker designed for a specific job and built to last when used within its intended ratings.

Key Features and Benefits

• 30-amp, 3-pole design for equipment requiring this specific electrical configuration.
• 10 kA I.C. at 240 VAC provides clearly defined ratings for matching an existing application.
• Type Q24 configuration helps narrow down compatibility when replacing an existing breaker.
• Two legs plug in; the third feeds through. This distinctive arrangement is an important detail when checking fit.
• At just 2.25 inches wide, the breaker maintains the physical profile required by compatible equipment.
• Well suited to form, fit, and functional replacement applications where keeping the existing system configuration matters.
• Built to last when installed correctly and used within its specified ratings.

Material Compliance and Certifications

• Specific certification and material compliance information was not provided in the available Q2431-30 specifications. UL, CSA, RoHS, or other certifications should not be assumed without verification. Check the markings on the breaker and any applicable manufacturer documentation to confirm certification or compliance requirements for your application.

Where It Works Best

• The Q2431-30 makes the most sense when maintaining or repairing compatible legacy electrical equipment that already calls for this particular Type Q24 breaker configuration. It’s especially useful in situations where changing the original equipment setup isn’t the goal—you need the correct breaker specifications for the existing system.
