The Square D FJA160205 belongs to the FJA frame series — a plug-in, molded-case circuit breaker rated for 347V AC, 25 kA interrupting capacity. This frame is designed for use in Square D commercial and industrial panelboards and switchboards that accept FJA/FJ-frame plug-in breakers, not residential QO or Homeline loadcentres. Its 347V single-pole rating makes it particularly well-suited for Canadian single-phase branch circuits in commercial distribution systems. Send us your panelboard model and we'll confirm fitment.
The FJA160205 is rated at 347V AC, which aligns with the standard Canadian single-phase line-to-neutral voltage on a 600V system — common in commercial and industrial buildings across Canada. Its 25 kA interrupting rating also meets the fault-current requirements of most commercial distribution panels.
The Square D FJA frame series is an older commercial/industrial line that can be difficult to source through standard electrical distributors. Northern Breaker Group specialises in exactly these types of hard-to-find and obsolete breakers — contact us for availability and lead time.
Direct cross-references depend on your panelboard's bus and plug-in configuration. Some Square D FA-frame and newer FH-frame breakers may be compatible, but voltage, interrupting rating, and physical fit must all be verified. We recommend contacting our team with your panel details so we can confirm a suitable replacement or supply the original FJA160205.
