F3020 - 20Amp Circuit Breaker

F3020 - 20 Amp Circuit Breaker

When you need a dependable, form-fit-function replacement for an existing electrical system, the F3020 circuit breaker delivers exactly what the job calls for. Built with an F-frame design, this 3-pole, 20-amp breaker is engineered to provide consistent circuit protection in commercial and industrial panelboards operating up to 480 VAC. Its thermal-magnetic trip mechanism responds to both overloads and short circuits, helping protect wiring and connected equipment under everyday operating conditions. With a non-interchangeable trip unit and a 40°C rating, this breaker is well-suited for installations where stable, predictable performance matters. Load terminals are included, simplifying installation and helping reduce setup time.
