B120DFH - 20A Dual Function Circuit Breaker

B120DFH  - 20A Dual Function Circuit Breaker

The B120DFH is a 20 Amp, single-pole bolt-on molded case circuit breaker designed to provide advanced circuit protection in your residential and commercial electrical distribution systems. Featuring dual-function protection, this breaker combines a Combination Type Arc-Fault Circuit Interrupter (AFCI) and a 5mA Ground-Fault Circuit Interrupter (GFCI) in one compact device, helping you to safeguard people, wiring, and connected equipment from multiple electrical hazards. With a 22kA interrupting capacity at 120/240VAC, the B120DFH is built for applications where enhanced fault protection and dependable performance are essential. Its bolt-on mounting design helps you ensure a secure connection within compatible panelboards, making it a practical choice for circuits requiring both arc-fault and ground-fault protection.

Key Features and Benefits

• Dual-Function Protection: Combines Combination Type AFCI and 5mA GFCI protection in a single breaker. Helps detect potentially dangerous arc faults and ground faults before they can lead to equipment damage, electrical fires, or shock hazards.
• 20 Amp Rating: Suitable for branch circuits requiring 20-amp overcurrent protection.
• Single-Pole Configuration: Designed for use on 120V circuits within compatible electrical distribution systems.
• 22kA Interrupting Capacity: Provides high fault-clearing capability at 120/240VAC, enhancing system protection during short-circuit conditions.
• Bolt-On Installation: Secure bolt-on mounting helps maintain reliable electrical connections and minimizes the risk of loosening due to vibration or system operation.
• Space-Saving Design: Integrates AFCI and GFCI functionality into one device, reducing the need for additional protective components.
