It is suited for single-phase branch-circuit protection in lighting panels and commercial distribution equipment.
Compatibility depends on the specific Square D panelboard or switchboard accepting the FJA plug-in frame. Send us your panelboard model and we'll confirm fit before you order.
The FJA160253 is an FJA-frame plug-in molded-case breaker rated for commercial and industrial Square D panelboards and switchboards — not residential QO or Homeline loadcentres.

347V is the standard single-phase voltage used in Canadian commercial lighting and distribution systems — it is one phase of a 600V three-phase wye system, which is the dominant commercial supply voltage in Canada. The FJA160253 is specifically designed for these higher-voltage Canadian commercial applications, making it a common choice for lighting panel branch circuits in offices, retail, and industrial facilities.
