Eaton gfcb125 - 25 A, 120 V Circuit Breaker | AmpState

The Eaton gfcb125 is a compact 25 A, 120 V molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Built for reliable performance in a variety of settings, this breaker helps you keep electrical systems safe and available from the first switch flip.

Why this breaker stands out

• Space-efficient design — a compact molded case profile makes the gfcb125 ideal for modern, tight panel installations where every inch counts.
• Thermal-magnetic trip unit — provides stable, repeatable protection performance by responding to both overloads and short circuits, helping prevent nuisance trips and ensuring fast isolation when faults occur.
• Plug-and-play compatibility — specifically designed to work with matching OEM load centers and panelboards, enabling smoother upgrades and maintenance with fewer compatibility concerns.
• Versatile application — suitable for residential panels, commercial distribution, and light industrial electrical controls where 25 A at 120 V protection is required.

What it protects and how it helps you

As a branch circuit protection device, the gfcb125 is your frontline defense against overcurrent and short circuits. By limiting current to 25 A at 120 V, it helps safeguard wiring, devices, and downstream circuits. The thermal-magnetic mechanism ensures that normal inrush and everyday load fluctuations don’t cause unnecessary interruptions, while still delivering prompt fault isolation when a real problem arises.

Ideal use cases

• Residential service panels where a reliable 25 A protection point is needed for subcircuits or specific appliances.
• Commercial panelboards that require compact, space-saving breakers with dependable protection characteristics.
• Light industrial control panels where consistent trip performance and compatibility with OEM load centers are priorities.
