Square D | QOB125GFI | Circuit Breaker | 25A | 1-Pole | 120V | Bolt-On

Introducing the Square D QOB125GFI — a purpose-built 25A, 1-Pole, 120V GFCI circuit breaker designed for safe, reliable protection in compatible panels. With its bolt-on mounting, this unit is an efficient choice for maintenance, retrofit, and replacement projects where precise specs matter.

Why choose the QOB125GFI for your electrical system?

• Ground-Fault Interruption (GFCI) protection: Built-in GFI technology detects imbalances between hot and neutral under 120V, rapidly interrupting current to prevent electrical shock in moisture-prone spaces, kitchens, baths, and outdoor outlets.
• Compact bolt-on design: The bolt-on mounting streamlines installation in compatible Square D panels, delivering a secure, stable connection with reduced on-site fuss.
• Precise specifications for reliable replacement: 25A, 1-Pole, 120V configuration ensures you’re matching the exact characteristics of the original breaker when upgrading or replacing aging components.
• Best compatibility reference: The part number QOB125GFI is your primary reference for compatibility—always confirm fit and ratings with your panel before ordering.

Ideal use scenarios

• Retrofit projects where you want to add or upgrade GFCI protection to existing 120V circuits without changing the panel layout.
• Replacement of a worn or obsolete 1-pole 25A breaker in Square D panels, preserving electrical characteristics while enhancing safety.
• New installations in areas requiring ground-fault protection, such as kitchens, bathrooms, or outdoor outlets, where moisture exposure is a consideration.

Practical guidance for installers and homeowners

• Verify panel compatibility by cross-referencing the panel’s listing with the QOB125GFI part number before purchase.
• Before installation, switch off the main breaker and follow standard safety procedures to protect personnel and equipment.
• When replacing an existing breaker, ensure the circuit’s amperage, voltage, and pole configuration match the QOB125GFI specifications to avoid nuisance trips or improper protection.
• Keep documentation on hand for future maintenance or panel upgrades; having the exact part number helps streamline compatibility checks later.

With the Square D QOB125GFI, you’re choosing a trusted combination of safety, reliability, and installation practicality. If your project requires precise 25A, 1-Pole, 120V GFCI protection in a bolt-on format, this breaker delivers the performance you expect from Square D—backed by clear compatibility guidance and a straightforward replacement path.
