Information About FA34090
The FA34090 is a Square D FA Series molded case circuit breaker built on the legacy F frame and manufactured by Schneider Electric. Its non-interchangeable thermal-magnetic trip mechanism provides long-time overload protection and instantaneous response to high-current short circuits. The breaker uses an I-Line connection on the line side and load-side lugs for aluminum or copper conductors, allowing integration with compatible Square D I-Line electrical distribution equipment. Schneider Electric discontinued this reference on November 25, 2022, and identifies BDA36090 as its recommended replacement.
Key Features:
- 90-Ampere Current Rating: Rated for 90 amperes at 40 degrees Celsius for commercial and industrial power distribution circuits.
- Three-Pole Configuration: Provides three protected poles for compatible three-phase electrical distribution applications.
- 480-Volt Rating: Designed for alternating-current systems operating at up to 480 volts.
- Thermal-Magnetic Protection: Uses a non-interchangeable thermal-magnetic trip mechanism to respond to overload and short-circuit conditions.
- Long-Time and Instantaneous Functions: Provides long-time protection against sustained overcurrent and instantaneous tripping during high-current faults.
- Interrupting Capacity: Rated for 25,000 amperes at 240 volts alternating current and 18,000 amperes at 480 volts alternating current.
- I-Line Connection: Uses Square D I-Line mounting on the line side and mechanical lugs on the load side for connection to the protected circuit.
- Legacy Equipment Support: Maintains the original FA I-Line form and electrical characteristics for servicing compatible existing distribution installations.
The FA34090 delivers the reliability and precision required for overload and short-circuit protection in compatible commercial and industrial I-Line power distribution systems.
