FIJ34100

The FIJ34100 is a Square D molded case circuit breaker rated for 100 amps at 480 volts with 3 poles, designed to protect industrial and commercial electrical circuits from overloads and short circuits. It belongs to Square D’s LA, LH, and Q4 family of molded case breakers, which provide dependable thermal-magnetic protection for distribution systems. This is an older design that is still used in many existing installations, which makes it a useful part for keeping those systems running. The FIJ34100 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. A 480 volt rating makes it suitable for the three-phase power systems found in many industrial plants and commercial buildings. Because the FIJ34100 comes from a legacy product line, and Schneider Electric lists no direct replacement, it is worth checking the part number, voltage, amp rating, and mounting against your equipment before ordering. This makes the FIJ34100 a practical choice for electricians and maintenance teams who need to replace a Square D breaker in an existing panelboard or switchboard and keep the system running, particularly where a matching replacement is hard to find.
