FAL34070 - 70 Amp Circuit Breaker

FAL34070 - 70 Amp Circuit Breaker

When you're maintaining an existing electrical system, the right replacement breaker needs to match the original specifications—not just the amperage. The Square D FAL34070 is a 70 Amp, 3-pole FA Series molded case circuit breaker designed for compatible 480 VAC applications where keeping the existing equipment configuration is important. This breaker uses a thermal-magnetic trip unit to handle both overload and short-circuit conditions, with the thermal element responding to sustained overcurrent and the magnetic element reacting quickly to fault conditions.
