The Square D FGA160253 is a 1-pole, 25A, 347V, 18kA plug-in molded-case circuit breaker from the FGA (F-Frame) series. As a commercial/industrial-grade MCCB, it is designed to mount in Square D panelboards and switchboards that accept F-Frame plug-in breakers — it is not intended for residential QO or Homeline loadcentres.
Typical applications include commercial distribution panels and branch-circuit protection in industrial settings where 347V single-pole protection is required (common in Canadian 347/600V systems). Send us your panelboard model and we'll confirm fit before you order.
Yes — 347V is the phase-to-neutral voltage of a standard Canadian 347/600V wye distribution system, widely used in commercial and industrial buildings across Canada. The FGA160253 is specifically rated for this voltage, making it well suited for branch-circuit protection in Canadian commercial installations.
The Square D FGA F-Frame series has seen limited availability through standard channels. Northern Breaker Group specializes in hard-to-find and obsolete breakers — we maintain stock of legacy Square D commercial breakers and can source the FGA160253 even when it's no longer readily available through regular distributors. Contact us or request a quote for current availability.
The FGA160253 carries an 18kA interrupting rating at 347V. This is suitable for many commercial branch-circuit applications, but you should verify that the available fault current at your panelboard does not exceed this value. If your system has higher short-circuit levels, a higher-interrupting-rated frame may be required — our team can help you assess your options.
