FCL34090 - 90 Amp Circuit Breaker Description

FCL34090 - 90 Amp Circuit Breaker

The FCL34090 is a 90 Amp three-pole thermal magnetic molded case circuit breaker used in electrical systems where the correct replacement specifications need to be maintained. This FCL frame breaker is commonly used in commercial and industrial equipment where matching your existing amperage rating, voltage requirements, and three-pole configuration is essential.

The breaker uses a thermal magnetic trip mechanism to provide protection against overloads and short-circuit conditions. The thermal element responds to sustained overcurrent, while the magnetic trip helps address fault conditions. Together, these functions provide the type of circuit protection expected from a molded case circuit breaker in properly rated electrical applications.

Key Features and Benefits
