Q2430-40 - 40 Amp Circuit Breaker

Q2430-40   - 40 Amp Circuit Breaker

Looking for a Q2430-40 circuit breaker to match an existing application? Also referenced as Q243040, this Type Q24 breaker is a 3-pole, 40-amp unit with a plug-on connection and a 10 kA AIC rating at 240VAC. It measures 4.81 inches high, 2.25 inches wide, and 2.5 inches deep. Those details are worth checking carefully, especially when you're working with older electrical equipment where the right fit matters just as much as the amp rating. The Q2430-40 is intended for compatible equipment that calls for this specific Q24 configuration. If you're replacing an existing breaker, compare the part number and ratings on the old unit with the specifications below. That simple check can help confirm you're looking at the right breaker for the job. When correctly matched to the application and installed within its specified ratings, this breaker is built to last and provide the form, fit, and function expected in compatible electrical systems.

Key Features and Benefits

• 40-amp rating for applications requiring this current.
• Three-pole design for compatible 3-pole electrical applications.
• Type Q24 configuration for equipment designed to accept this breaker type.
• Plug-on connection to match the required mounting and connection arrangement.
