FAL32045 - 45 Amp Circuit Breaker

FAL32045 - 45 Amp Circuit Breaker

When you're replacing a circuit breaker in an existing panel, the details matter. A breaker with the wrong amperage, pole count, or terminal setup can create unnecessary complications. The FAL32045 is a 45 Amp, 3-pole FA Series thermal-magnetic molded case circuit breaker built for compatible electrical equipment where matching the original breaker specifications is important.

The breaker uses a thermal-magnetic trip system that handles two common types of overcurrent protection. The thermal element responds to overload conditions that build over time, while the magnetic element reacts to sudden short-circuit events. This combination helps protect connected circuits while allowing existing equipment to remain configured as it was designed.
