FA34045 - 45 Amp Circuit Breaker Description

FA34045 - 45 Amp Circuit Breaker

The FA34045 is a 45-amp, 3-pole thermal-magnetic molded-case circuit breaker used in compatible I-Line panelboards. When you're replacing a breaker in an existing electrical system, getting the details right matters. The amperage rating, pole configuration, interrupting capacity, and panel compatibility all need to line up with the original equipment. This FA Series breaker is intended for applications where maintaining the existing installation is the priority. The thermal-magnetic trip unit protects against both overloads and short circuits by responding to different fault conditions. Built to last, this molded-case circuit breaker provides the electrical characteristics and fit required to keep compatible FA Series I-Line panelboard systems in service.
