FJA160205

The FJA160205 is a Square D molded case circuit breaker rated for 20 amps at 347 volts with 1 pole, designed to protect lighting and branch circuits in commercial and industrial buildings. The 347 volt rating is used on the 600Y/347 volt systems found in many Canadian and large commercial facilities, where lighting and other single-phase loads run on 347 volts. Its single-pole design protects one circuit, and its compact size makes it a good fit where many circuits share a panel. The FJA160205 uses a thermal-magnetic trip, which combines two kinds of protection. The thermal element responds to sustained overloads, while the magnetic element trips instantly on a short circuit, so the breaker can clear a fault quickly and still tolerate the brief surges that equipment draws at startup. It is an I-Line plug-in breaker, which means it clips directly onto the bus in Square D I-Line panelboards and switchboards, making it quick to install or replace without wiring the line side. Because the FJA160205 comes from a legacy product line (Schneider’s PowerPact B-frame breakers are the current successors for this rating), it is worth checking the part number, voltage, amp rating, and phase connection against your equipment before ordering. This makes the FJA160205 a practical choice for electricians and maintenance teams who need to replace a Square D F-frame breaker in an existing I-Line panelboard and keep the system running.
