F3015 - 15Amp Circuit Breaker

F3015 - 15 Amp Circuit Breaker

If you’re working on an existing electrical system, you already know this: getting the exact breaker matters. The F3015 circuit breaker is built for that purpose—matching the form, fit, and function required in F-frame applications without guesswork. This 15-amp, 3-pole thermal-magnetic breaker is designed to handle everyday protection against overloads and short circuits in commercial and industrial environments. With a 14k A.I.C. rating at 480VAC, it’s suited for systems where interruption capacity needs to meet established specifications—not exceed them, not fall short. Because it uses a non-interchangeable trip unit, what you see is what you get—fixed, consistent protection that aligns with the original system design. It’s rated for 40°C conditions and comes with load terminals included, helping simplify installation when replacing a worn or failed unit. Bottom line: if you need a breaker that fits right, connects right, and performs as expected in an existing setup, the F3015 checks those boxes.
