FDA34100 - 100Amp Circuit Breaker

FDA34100 - 100Amp Circuit Breaker

When you're replacing a circuit breaker in an existing electrical system, getting the right match matters. The FDA34100 Square D circuit breaker is a 100 Amp, 3-pole molded case circuit breaker designed for use in compatible Square D I-Line panelboards and distribution equipment. If your panel already uses an FDA-series breaker, this model offers the same plug-in connection style, pole configuration, and electrical ratings to help keep the original system layout intact.

If you're replacing an existing 100 Amp Square D I-Line breaker, the FDA34100 offers the compatibility, connection style, and protection characteristics needed to keep your electrical distribution system operating as originally designed.
