Why customers choose TaskHolt Tools

Overview

Discover the CUTLER-HAMMER BRN120AF, a 20-amp, single-pole arc fault circuit breaker designed to boost safety in your electrical panel. This UL Listed device supports 120-volt installations and is capable of pairing with 240-volt systems in mixed configurations, making it suitable for many residential setups and light commercial applications.

Why ARC Fault Protection Matters

ARC Fault Circuit Interrupters (AFCIs) add a layer of vigilance by monitoring for irregular arcing on branch circuits. The BRN120AF combines AFCI protection with targeted detection of persistent, low-current arcing faults, down to 5 amps. This proactive approach helps address the kinds of arcing that can occur in cords, outlets, and connected devices—potentially reducing the risk of nuisance fires and property damage without requiring constant manual checks.

  • Combination AFCI for branch-circuit arcing detection
  • Direct detection of low-current arcing faults (down to 5 amps)
  • Mitigates hazards associated with cords and outlets on the protected circuit
  • 1-pole design (120V) with compatibility for 240V systems in mixed setups
  • 10kAIC interrupting capacity for robust performance under fault conditions
  • Pigtail neutral configuration for flexible, straightforward wiring

Practical Use Scenarios

Consider this breaker when upgrading existing panels or wiring new circuits in living spaces where AFCI protection is recommended. Its compact, single-pole form helps with straightforward installation and panel organization, while the included pigtail neutral offers wiring flexibility in variable panel layouts.

  • Bedrooms, living rooms, and other living spaces where AFCI protection improves safety
  • Renovations or new installations needing UL Listed arc-fault protection
  • Panels that favor a neutral-neutral pigtail wiring approach for easier connections

Technical Highlights

  • Voltage: 120V / 240V
  • Current rating: 20A, 1-pole
  • Interrupting capacity: 10kAIC
  • UL Listed for reliable certification and compliance
  • Made in the Dominican Republic

In short, the BRN120AF offers substantive arc-fault protection with practical installation features. While outcomes depend on your overall electrical system, this device is designed to be a capable, code-aligned component in safeguarding residential circuits.
