The Square D FA14020A is a single-pole molded case circuit breaker from Schneider Electric's I-Line family, designed for thermal magnetic overcurrent protection in branch circuits. It is rated for 20A at 277VAC with an 18kA interrupting capacity, providing LI (Long-Time and Instantaneous) trip functions for coordinated fault clearing. This F Frame breaker measures 6.4 in x 1.5 in x 4.13 in (H x W x D), weighs 6 lb, and features an I-Line style plug-in connection for secure panel mounting. It operates within a temperature range of -13°F to 158°F (-25°C to 70°C) and is manufactured in Mexico. Typical applications include industrial and commercial power distribution systems requiring reliable branch circuit protection.
