Eaton GBH1025 25A 600V 1-Pole Bolt-On Circuit Breaker

The Eaton GBH1025 is a compact, reliable 25A, 600V, 1-pole bolt-on molded case circuit breaker designed to protect your electrical distribution by interrupting fault currents and preventing equipment damage. Built for panelboards and load centers, this breaker delivers consistent protection across residential, commercial, and light industrial settings.

What makes the GBH1025 stand out

• Secure bolt-on mounting provides a rigid, vibration-resistant connection to the bus, helping maintain precise alignment and dependable performance even in environments with movement or vibration.
• Thermal-magnetic trip unit delivers stable, repeatable protection by responding to both gradual overcurrents and sudden short circuits, reducing nuisance trips while safeguarding circuits.
• OEM compatibility is designed to work with matching load centers and panelboards, ensuring a seamless, code-compliant fit when upgrading or expanding existing systems.
• Versatile application ideal for residential panels, light-commercial distribution, and small industrial applications where compact, robust overcurrent protection is required.

Technical snapshot

• Manufacturer: Eaton
• Part number: GBH1025
• Type: Thermal-magnetic molded case circuit breaker
• Amperage rating: 25A
• Voltage rating: 600V
• Number of poles: 1
• Mounting style: Bolt-on
• Application: Branch circuit overcurrent and short-circuit protection

Practical use cases

• Upgrading a residential panel to add new circuits with reliable overcurrent protection.
• Replacing a less-secure plug-in breaker in a panel where a bolted connection offers greater resistance to vibration and movement.
• Powering small office or storefront circuits where 25A protection at 600V provides appropriate circuit isolation and safety margins.

Why choose this breaker over alternatives

With its bolt-on design, the GBH1025 delivers a more rigid bus connection, which translates to fewer electrical arc risks and more consistent trip performance in environments subject to vibration or panel movement. The built-in thermal-magnetic protection is tuned for reliable response, helping you avoid nuisance trips while still quickly interrupting fault conditions. And, because it’s designed to pair with matching OEM load centers and panelboards, you’ll enjoy a smoother installation and a safer, code-compliant system.

Who should consider the Eaton GBH1025

Electrical professionals installing or upgrading panelboards in homes, small commercial spaces, or light-industrial facilities will benefit from the robust bolt-on mounting, dependable protection, and OEM-compatible design. It’s a solid choice for projects that demand durable, long-lasting overcurrent protection in a compact, single-pole format.

Installation notes and tips

• Confirm panelboard compatibility with the Eaton GBH1025 to ensure seamless mounting and protection coordination.
• Ensure the circuit requires 25A protection at up to 600V and that a 1-pole breaker aligns with the circuit layout.
• During installation, secure the bolt-on connection firmly to maintain a stable bus contact and reliable trip performance.
• Keep a spare GBH1025 on hand for quick swaps in maintenance or upgrades, reducing downtime on critical circuits.
