Schneider Electric FA32040 Molded Case Circuit Breaker

Schneider Electric's Square D FA32040 molded-case circuit breaker is a 3-pole, 40 A unit designed for 240 V service with a 10 kA interrupting rating, providing thermal-magnetic protection for three-phase circuits. It features I-Line plug-in mounting for quick, field-verified installation in compatible Square D panels and executes long-time and instantaneous trip functions to protect conductors and equipment from overloads and short circuits. The FA32040 is part of the FA family, a legacy Square D line, and supports options including a shunt-trip variant for remote tripping and control in industrial or commercial applications such as motors, pumps, HVAC equipment, and other three-phase loads up to 40 A. This MCCB is commonly used where space-constrained, robust overcurrent protection is needed in distribution panels, offering a compact form factor with standard three-pole protection for 240 V systems.
