Q2430-40 - 40 Amp Circuit Breaker

Q2430-40   - 40 Amp Circuit Breaker

The Q2430-40 is a 40 amp, 3-pole circuit breaker used in panels that take a Q24 frame. It’s typically installed as a replacement when an existing breaker of the same size and rating needs to be swapped out. Nothing fancy here. It’s made to fit, connect properly, and protect the circuit the way the original breaker did. This breaker uses a plug-on connection, so it installs directly into the panel without extra parts. That saves time during service work and helps avoid fitment issues. It’s commonly used in residential systems and lighter commercial setups where a 40 amp, three-pole breaker is required.
