The FKA160303 SQUARE D 1P 30A 347V B PH I LINE is a reliable circuit breaker designed for electrical systems requiring high performance and safety. With its single-pole configuration and a 30A capacity, this breaker is ideal for residential and commercial applications. Ensure optimal protection and functionality for your electrical installations with this trustworthy component.
Unlike Square D QO or Homeline residential breakers, the FKA160303 belongs to the industrial FK frame series, rated for 347V and a high 65kA interrupting capacity. This makes it suitable for commercial and industrial 347/600V distribution systems — not typical home loadcentres.
The Square D FK frame series is considered a legacy/hard-to-find line. Northern Breaker Group specializes in sourcing obsolete and discontinued breakers like the FKA160303. Contact our Calgary, Edmonton, or Vancouver counter or request a quote online and our team will locate available stock for you.
A breaker rated for 347V can generally be applied on lower-voltage systems (e.g., 120/208V), as it meets or exceeds those voltage requirements. However, you should always verify with your panelboard specifications and consult a licensed electrician to ensure the application meets Canadian Electrical Code (CEC) requirements for your installation.
