The Square D FA17060C is a 1-pole, 60A, 347V plug-in circuit breaker from the Square D FA (I-Line/General Duty) frame, rated for 14kA interrupting capacity. This is a commercial and industrial-grade molded-case breaker designed to mount in compatible Square D I-Line panelboards and switchboards — it is not intended for residential QO or Homeline loadcentres. The 347V rating makes it particularly suited for single-phase Canadian commercial lighting circuits (347V phase-to-neutral on a 600V system).
Exact panelboard compatibility depends on your enclosure's busway type and interrupt rating — send us your panelboard model and we'll confirm fit.
The FA17060C is rated for 347V, which is the standard phase-to-neutral voltage on Canadian 600V (347/600V) three-phase distribution systems. This makes it a common choice for commercial and industrial lighting panel circuits across Canada, where 347V fluorescent and LED lighting feeds are the norm.
The FA17060C is a plug-in style breaker, designed to snap onto the I-Line bus in compatible Square D I-Line panelboards. It is not a bolt-on type, so it must be installed in a panelboard with a matching I-Line plug-in bus — using it in a bolt-on-only panel is not correct. If you're unsure which style your panel requires, contact us with your panelboard model number.
