Square D Homeline 40 Amp Mini 2‑Pole GFCI Circuit Breaker Residential

Description

Product Overview

The Square D Homeline 40 Amp 2‑Pole GFCI mini circuit breaker is engineered to deliver dependable protection for residential electrical systems. Constructed with high‑quality copper contacts, this breaker ensures low resistance and superior conductivity, reducing heat buildup and extending service life. With a 10 kA breaking capacity, it can safely interrupt fault currents, protecting wiring and connected equipment from damage. The breaker is UL‑listed, confirming compliance with rigorous safety standards, and features a compact snap‑on mounting design that fits seamlessly into Homeline load centers. Its 2‑pole configuration supports 120/240 V circuits, making it suitable for demanding appliances such as dryers, ranges, and air‑conditioners. The integrated Class A ground‑fault protection detects imbalances as low as 5 mA, providing an added layer of safety for people and property.

Usage

This breaker is ideal for homeowners, electricians, and contractors who need a reliable solution for protecting high‑current circuits in single‑family homes, townhouses, and small multifamily dwellings. It can be installed in new construction projects or used to upgrade existing panels where enhanced ground‑fault protection is required. The snap‑on mounting mechanism simplifies installation, allowing the breaker to be secured in a matter of minutes without the need for additional tools. Once installed, the breaker provides continuous monitoring of current flow and automatically trips in the event of overload, short circuit, or ground‑fault conditions, helping to prevent electrical fires and equipment failure. Its robust design also makes it suitable for retrofit applications in older homes where modern safety standards must be met.

FAQ

What size wire can be used with this breaker?

The breaker accepts copper conductors ranging from 12 AWG to 10 AWG, providing flexibility for typical residential wiring applications.

Can this breaker be used in non‑Homeline panels?

While the breaker is optimized for Homeline load centers, its snap‑on design may be compatible with other panels that support plug‑in mounting, but verification with the panel manufacturer is recommended.

How does the GFCI function differ from a standard circuit breaker?

In addition to standard overload and short‑circuit protection, the GFCI monitors the balance between hot and neutral currents. If an imbalance indicative of a ground fault is detected, the breaker trips instantly, protecting users from electric shock.

Is a separate neutral pigtail required for installation?

No. The Homeline GFCI breaker includes an integrated pigtail that connects directly to the panel’s neutral bar, simplifying wiring and ensuring proper grounding.

What is the warranty coverage for this product?

Square D provides a lifetime warranty for the breaker when installed in a Homeline load center, covering defects in material and workmanship under normal residential use.
