FA36090 - 90 Amp Circuit Breaker

FA36090 - 90 Amp Circuit Breaker

The FA36090 is a 90 Amp, 3-pole thermal magnetic molded case circuit breaker designed for use in compatible FA Series I-Line panelboards. When you're maintaining existing electrical distribution equipment, matching the original breaker specifications is important for preserving the system layout and intended operation. This breaker provides the form, fit, and function needed for compatible installations while delivering thermal-magnetic protection against overloads and short-circuit conditions.

Built to last, this molded-case circuit breaker is a practical choice for commercial and industrial facilities that need to maintain compatibility with FA Series electrical distribution equipment without changing the original panelboard configuration.
