The FH16020C SQUARE D 1P 20A 277V Circuit Breaker is designed for reliable protection in commercial and industrial applications. This single-pole breaker provides 20 amps of capacity, ensuring efficient and safe operation at 277 volts. Ideal for both new installations and replacements, it offers durability and peace of mind for your electrical system.
The FH16020C operates at 277V (versus the 120/240V rating of QO and Homeline breakers) and carries a high 65kA interrupting rating. It is an FH-frame commercial/industrial plug-in breaker, making it unsuitable as a drop-in replacement in residential QO or Homeline loadcentres.
The Square D FH-frame series can be difficult to source through standard distribution channels. Northern Breaker Group specializes in hard-to-find and obsolete breakers — contact us for current stock availability and lead times on the FH16020C.
If your existing breaker is a Square D FH-frame plug-in unit with matching voltage (277V) and the panel bus can accommodate a 1-pole, 20A breaker, the FH16020C is generally a direct replacement. Always verify the panelboard's interrupting rating meets or exceeds 65kA and that the bus stab configuration matches — reach out to us with your panel details to confirm.
