B115DFHH - 15A Dual Function Circuit Breaker

B115DFHH  - 15A Dual Function Circuit Breaker

The B115DFHH is a 15 amp, single pole bolt-on circuit breaker built for applications where safety and code compliance matter. It combines Combination Type AFCI protection with 5mA Class A GFCI protection in one breaker, helping protect both wiring and people from arc faults, ground faults, and overload conditions. Rated at 65kA interrupting capacity at 120/240VAC, this breaker is suitable for panels where higher available fault current is present. Because it’s a bolt-on molded case breaker (HBFGA2 frame), it installs with a secure mechanical connection to compatible panelboards, reducing movement and helping maintain consistent contact over time. Instead of using separate AFCI and GFCI devices, this dual function unit simplifies the setup while meeting modern branch circuit protection requirements.

Key Features and Benefits

• Dual Protection in One Breaker: Combination AFCI helps detect dangerous arc faults, while built-in 5mA GFCI protection reduces shock risk.
• 15 Amp, Single Pole: Ideal for standard 120V branch circuits.
• 65kA @ 120/240VAC Interrupting Rating: Designed for systems with higher available fault current.
• Bolt-On Mounting: Creates a secure, stable connection in compatible panels.
• Space Efficient: Combines two protective functions into a single device.
• Molded Case Construction: Built for consistent, reliable performance.
