FAL340901021 - 90 Amp Circuit Breaker

FAL340901021 - 90 Amp Circuit Breaker

Not every replacement breaker is the same, especially when the original installation includes a factory-installed shunt trip. The Square D FAL340901021 is a 90 Amp, 3-pole FA Series molded case circuit breaker built for compatible 480 VAC systems where remote tripping is part of the equipment's original design. Matching the catalog number and accessory configuration helps you keep maintenance straightforward and avoids unnecessary changes to the existing electrical system.
