The FKA160155 SQUARE D 1P 15A 347V C PH I LINE is a reliable single-pole circuit breaker designed for optimal performance in commercial and residential applications. With a current rating of 15A and voltage of 347V, this unit ensures safety and efficiency in electrical systems. Ideal for various setups, it offers dependable protection.
The FKA160155 belongs to Square D's F-Frame commercial/industrial series, rated at 347V and 65kA interrupting capacity — significantly higher than a residential QO (120/240V, 10kA typical). It is built for commercial panelboards and switchboards, not residential loadcentres, and should not be substituted with a QO or Homeline breaker in higher-voltage or higher-fault-current applications.
Certain FKA-series breakers have been phased out or replaced by updated Square D product lines, making them challenging to source through standard distribution channels.

Yes — the FKA160155 is rated at 347V, which corresponds to the phase-to-neutral voltage of a 347/600V system common in Canadian commercial and industrial buildings. Always verify that your panelboard's voltage and bus rating match, and consult a licensed electrician to ensure the installation meets the Canadian Electrical Code (CEC) requirements for your jurisdiction.
