The FA17060B SQUARE D 1P 60A 347V B PH I LINE is a reliable single-pole circuit breaker designed for maximum efficiency in electrical systems. With a rating of 60A at 347V, it offers superior protection against overloads and short circuits. Ideal for commercial and industrial applications, ensuring safety and performance.
347V is a common Canadian single-phase voltage — it is the phase-to-neutral voltage of a 600V three-phase wye system. The FA17060B's 347V rating makes it well-suited for commercial and industrial branch circuits in Canadian 600V wye-connected distribution systems, such as lighting panels fed from a 347/600V transformer.
Square D's FA-frame breaker line has largely been superseded by newer MCCB series. If the FA17060B is discontinued or hard to find through regular channels, Northern Breaker Group specialises in exactly this — sourcing obsolete and hard-to-find breakers across Canada. Contact our Calgary, Edmonton, or Vancouver counters for availability and lead time.
Directly replacing an FA-frame breaker with the FA17060B is possible if the voltage rating (347V), amperage (60A), pole count (1P), and interrupting rating (14kA) meet or are compatible with the original breaker's specifications and the panelboard's requirements. Always verify the replacement meets the panel's bus rating and any labelling requirements under CSA/CEC standards — reach out to us and we can help confirm suitability for your application.
