BF240AH - 40Amp Circuit Breaker Description
BF240AH - 40Amp Circuit Breaker
The Siemens BF240AH is a 40 amp, 2-pole GFCI circuit breaker designed for use in 120/240VAC electrical distribution systems where both overcurrent protection and personnel ground fault protection are required. Part of Siemens' BLHF series, this molded case circuit breaker combines thermal-magnetic circuit protection with Class A 5mA ground fault protection, helps safeguard your equipment and personnel from overloads, short circuits, and ground fault conditions. With a 22kAIC interrupting rating, the BF240AH is well suited for commercial, industrial, institutional, and other demanding electrical applications where higher fault current levels may be present.
Built for panelboard mounting, the BF240AH provides the form, fit, and performance expected from Siemens low-voltage power distribution products. Its compact design makes it a practical choice for maintenance, retrofit, and replacement projects where maintaining system compatibility is essential. Whether you're installing it in service areas, maintenance facilities, commercial buildings, or other locations requiring GFCI protection, this breaker delivers dependable circuit protection while helping facilities meet applicable electrical safety requirements.

Where It Works Best
- The Siemens BF240AH is commonly used in commercial buildings, healthcare facilities, schools, industrial plants, maintenance areas, utility spaces, workshops, and other environments where 120/240VAC branch circuits require both overcurrent and ground fault protection. Its 22kAIC rating makes it particularly well suited for installations where available fault current levels exceed the capabilities of standard interrupting-rated breakers. The BF240AH is also an excellent choice for replacement applications where matching the original breaker's ampacity, pole configuration, voltage rating, GFCI protection level, and interrupting capacity is critical for maintaining system performance and safety.
