QOB250GFI - 50A Circuit Breaker

QOB250GFI - 50A Circuit Breaker

The QOB250GFI is a 2-pole, 50-amp bolt-on GFI circuit breaker for 120/240VAC electrical systems. It combines overcurrent protection with built-in ground fault protection, making it a good fit for circuits where personnel safety is a priority. With a 10k A.I.C. rating, it is intended for use in your compatible bolt-on panelboards in commercial and industrial applications. Because it uses a bolt-on mounting design, the breaker stays securely attached to the panel, helping maintain a dependable electrical connection. It's commonly installed as a replacement for an existing breaker or as part of a panel upgrade when a compatible GFI breaker is required. As with any electrical component, confirm compatibility with your equipment before installation.
