Authenticity and safety commitments

ABB acquired GE Industrial Solutions in 2018, and residential products are now offered as ABB, GE by ABB, or ABB branded options. Look for authentic logos and third-party certifications (UL, IC, Intertek) to help verify genuineness.

Real-world use cases

In bathrooms or kitchens, near water sources, this GFCI breaker can add protective coverage to outlets and connected devices. In garages and outdoor spaces, it supports outlets and tools during seasonal projects, helping manage ground fault risks in exposed environments.

Why consider this breaker

While no device guarantees fault-free operation, the combination of fast fault detection, automatic self-test, and durable construction supports safer everyday electrical use and reliable protection over time.
