The FJA160203 is a 1-pole thermal-magnetic molded case circuit breaker from Schneider Electric’s Square D F-Frame series, designed for branch-circuit protection in 347V electrical systems common in commercial and industrial lighting and equipment applications. Rated for 20 at 347, it provides dependable overload and short-circuit protection in a compact, single-pole package. Its I-Line style plug-in mounting allows it to install directly into compatible I-Line panelboards and switchboards, making it a practical choice for both new installations and replacements.
Electrically, the FJA160203 uses a thermal-magnetic trip mechanism, combining heat-sensitive overload protection with magnetic instantaneous response for fast interruption of short-circuit faults. It carries an interrupting capacity of {aic rating}, giving it dependable fault-current protection on 347V circuits where standard 120/240V breakers would not be rated for the application.
Mechanically, the FJA160203 is built on the compact F-Frame platform with an I-Line plug-in connection, so it mounts directly to the panelboard bus without separate line-side wiring. Its molded case and toggle operator allow straightforward manual ON/OFF control and reset after a trip event. The FJA160203 is a dependable option for maintaining or expanding existing Square D I-Line distribution equipment.
