BF120AHH - 20Amp Circuit Breaker

BF120AHH - 20Amp Circuit Breaker

The Siemens BF120AHH is a 20 Amp single-pole GFCI circuit breaker built for applications where dependable ground fault protection matters. Designed for 120V systems, this breaker helps protect both your equipment and personnel by detecting ground fault conditions quickly and helping reduce the risk of electrical shock. With a 65kA interrupting rating, it’s commonly used in commercial and industrial panelboards where higher fault current capacity may be required.

Part of the Siemens HBLF2 series, the BF120AHH combines ground fault protection with molded case circuit breaker functionality in one compact unit. Its 5mA GFCI sensitivity makes it suitable for circuits where personnel protection is important, while the panelboard mounting design helps simplify installation in compatible systems. The compact footprint is also useful in tighter panel layouts where space can be limited.

Whether used in maintenance projects, facility upgrades, or existing electrical distribution systems, the BF120AHH is designed to provide consistent protection without overcomplicating installation or operation.
