The FH16025B Square D 1P 25A 277V B PH I LINE is a reliable single-pole circuit breaker designed for efficient electrical protection. Offering a maximum current rating of 25 amps, this breaker is perfect for residential and commercial applications. Trust in its performance for robust and safe power management in your systems.
The FH16025B uses Square D's I-Line plug-in mounting configuration, which is designed for commercial and industrial Square D I-Line panelboards and switchboards — not residential QO or Homeline loadcentres. If you're unsure whether your panel accepts I-Line breakers, send us your panel model and our team will confirm compatibility.
The 277V rating is common in commercial and industrial facilities where lighting circuits and other loads are fed from a 480V/277V wye distribution system. The FH16025B is specifically designed for these higher-voltage single-phase branch circuits, making it a go-to choice for commercial lighting panels and similar applications.
Square D's FH frame series breakers can be difficult to find through standard supply channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers — if the FH16025B is discontinued or out of stock elsewhere, we can often source verified surplus or reconditioned units. Contact our Calgary, Edmonton, or Vancouver counters for availability and to request a quote.
