FA34050 **Old Style** - 50 Amp Circuit Breaker

FA34050 **Old Style** - 50 Amp Circuit Breaker

The FA34050 Old Style is a 50-amp, 3-pole thermal-magnetic molded-case circuit breaker used in compatible I-Line panelboards. When you're working with existing electrical distribution equipment, replacing a breaker with the correct specifications helps maintain the original system configuration. This FA Series breaker is intended for applications requiring the same amperage rating, three-pole arrangement, and panel compatibility. 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.
