FAL34020 - 20 Amp Circuit Breaker

FAL34020 - 20 Amp Circuit Breaker

When you're matching a replacement breaker, the small details matter. The amp rating is only one piece of the puzzle—pole count, mounting style, terminals, and voltage rating all need to line up with the equipment already in place. The FAL34020 is a 20 Amp, 3-pole FA Series thermal-magnetic molded case circuit breaker made for compatible 480V electrical distribution applications where keeping the original setup intact is important.

This breaker uses a thermal-magnetic trip design with separate responses for different fault conditions. The thermal element handles overload conditions that build over time, while the magnetic element responds quickly to short-circuit events. Each pole includes both sensing elements, providing the type of protection expected from FA Series molded case breakers.
