    Square D™ Dual Function Circuit Breakers

    Why Dual Function Circuit Breakers Are Safer

    Designed to help keep homes and families safe from electrical hazards that were previously undetectable.

US Electrical Fires 2010-2014*

  • 32,000 Annual fires in home electrical systems.
  • 400 / 1180 400 civilian deaths. 1,180 civilian injuries.
  • $1.2 Billion Direct property damage.

Safer Homes With Dual Function Circuit Breakers

Electrical Fires (183408629-IC-410x230)

The innovative Square D QO™ and Homeline™ Dual Function Circuit Breakers combine two critical, state-of-the-art technologies — Combination Arc Fault and Ground Fault (Class A) Protection — into one circuit breaker, making it the safest solution for the home. Dual Function Circuit Interrupters provide a higher level of protection than any other residential circuit breaker. Where installed, these devices protect the entire circuit, not just a part of the circuit like electronic receptacles do (GFCI or AFCI).

TIME SAVER Diagnostics Feature

Troubleshoot Circuit Issues
All Dual Function circuit breakers are equipped with TIME SAVER Diagnostics. This feature helps contractors and homeowners identify the type of fault that last occurred and get detailed circuit information at the touch of a button. The TIME SAVER Diagnostics sequence is simple and easy to use and requires no tools or special training. Eliminate the guesswork with TIME SAVER Diagnostics.

Why Homes Need Dual Function Circuit Breaker Protection

Today, our dependence on electricity is increasing, and we are expecting more out of our home’s electrical system. According to the U.S. Census Bureau, half of the homes in use in the United States were built prior to 1973, before many of the electronics and appliances we use today were even invented. Unfortunately, our increased demands for energy can overburden an older home’s electrical system causing fires or electrocutions.

The National Electrical Code (NEC) requirements for arc fault protection also continue to expand. The NEC now requires protection for bedrooms, family rooms, living rooms, dens, home offices, and other similar rooms. Square D™ by Schneider Electric™ Electrical Distribution System provides reliable protection against electrical hazards in the home that may have gone undetected in years past.

Electrical Fires and Older Homes

More than 30,000 electrical fires occur in homes every year, resulting in hundreds of deaths, injuries, and more than a billion dollars in property damage. Many electrical fires occur in aging homes. Electrical fires can be devastating and lethal since they often occur when we least expect them, and in locations that may be hidden from view.

Fire Statistics Support Using AFCIs

Electrical fires are a significant issue. The NFPA Home Electrical Fires Fact Sheet indicates that wiring and related equipment were involved in 63% of electrical fires and half of the associated deaths in 2007-2011. Frequently, it is argued that fires only occur in older homes. However, new homes become older homes. It is critical to install the AFCIs (arc fault circuit interrupters) during construction so that they can protect homes from the start. The U.S. Department of Housing and Urban Development (HUD) recommends promoting AFCIs as one of the many devices that can be used to prevent burns and fire related injuries, and cites the 1999 CPSC Report recommending the use of AFCIs to "prohibit or reduce potential electrical fires from happening."
