Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

ABB 20A Ground Fault 2-Pole Circuit Breaker with Self-Test is a compact, plug-in GFCI solution designed for indoor panels that demand reliable protection for 120/240V circuits. Its two-pole design guards both live conductors, making it ideal for multi-wire branch circuits and 240V equipment, while the built-in self-test keeps protection ready when you need it most.

  • Two-pole, 20 Amp GFCI — protects both hot legs in 120/240V circuits, ensuring sensitive equipment and outlets stay shielded from ground faults.
  • Self-test functionality — continuously verifies the sensing circuitry and trip mechanism, reducing maintenance and eliminating guesswork about protection status.
  • Plug-in mounting — quick and straightforward replacement in compatible panels, minimizing installation time and downtime.
  • Indoor use, UL Listed — designed for indoor panel environments with standard electrical code compliance.
  • Compact footprint — measurements of 2 in wide by 3.3 in high by 2.4 in deep fit neatly into crowded panel spaces.
  • Includes breaker — packaged as a complete 2-pole GFCI breaker ready for installation.
  • Voltage flexibility — supports 120/240V operation to cover a broad range of residential and light commercial needs.

Who needs this breaker? Homeowners, electricians, and property managers who require dependable ground-fault protection for multi-wire circuits or 240V loads in indoor panels. It’s particularly valuable in kitchens, laundry areas, basements, and workshops where moisture and high-demand appliances raise the risk of ground faults. With ABB’s precision engineering, you gain faster protection, fewer nuisance trips, and peace of mind that the critical circuits in your space stay safeguarded.

Why choose the ABB 20A Ground Fault 2-Pole Circuit Breaker with Self-Test?
