FA34020 - 20 Amp Circuit Breaker

FA34020 - 20 Amp Circuit Breaker

The FA34020 is a 20-amp, 3-pole thermal-magnetic molded-case circuit breaker used in compatible I-Line panelboards. When you're servicing an existing electrical distribution system, the right replacement often comes down to matching the original specifications. This FA Series breaker is suited for applications that require the same amperage rating, three-pole configuration, and panel compatibility as the existing equipment. The thermal-magnetic trip mechanism responds to both overload conditions and short circuits, helping to protect connected circuits during normal operation. Built to last, this molded-case circuit breaker provides the proper fit and electrical characteristics for compatible FA Series I-Line panelboard installations in commercial and industrial environments.
