Product FAQs
4 answersWhat does the "B" suffix in the FY14015B catalog number indicate?
The "B" indicates that this 1-pole breaker is factory-configured specifically for a Phase B connection within Square D I-Line panelboards and switchboards.
What is the modern replacement for the Square D FY14015B?
The FY series is a legacy F-Frame circuit breaker. Schneider Electric has officially replaced these older F-Frame models with the modern PowerPact B-Frame series for new installations and panel upgrades.
How does the FY14015B mount into the panelboard?
It features an I-Line style plug-in connection. This allows the breaker to securely snap directly onto the busbar of compatible Square D I-Line equipment, providing both the electrical phase connection and mechanical mounting without requiring bolt-on hardware.
Is this circuit breaker suitable for switching lighting loads?
Yes, 15-amp FY-frame breakers are SWD (Switching Duty) rated. This means the breaker is approved to be used as a switch for controlling fluorescent lighting circuits on a regular basis without damaging the internal mechanism.
