FA32090 - 90 Amp Circuit Breaker

FA32090 - 90 Amp Circuit Breaker

The FA32090 is a 90 Amp, 3-pole thermal magnetic molded case circuit breaker used in compatible I-Line panelboards. When you're maintaining an existing electrical system, finding a breaker that matches the original specifications is often the most important step. This FA Series breaker is suited for applications where the amperage rating, three-pole configuration, and panel requirements need to remain consistent with the existing installation. The thermal-magnetic trip mechanism provides protection against both overload and short-circuit conditions, helping protect connected circuits during normal operation.
