Eaton Cutler-Hammer GHB3025 25A 3P 480V Circuit Breaker, Bolt-On | AmpState

Introducing the Eaton Cutler-Hammer GHB3025 25A 3P 480V Bolt-On Circuit Breaker—built for dependable, on-site protection in demanding electrical distributions. Designed to slot into panelboards and load centers with the original BOM in mind, this unit is the smart choice for replacement projects and stocking spares that keep critical systems humming without delay.

• Bolt-On mounting delivers fast, secure installation and cleaner wiring in tight spaces, reducing downtime during service and upgrades.
• 3-pole design provides balanced protection across all phases, essential for reliable operation in three-phase 480V networks.
• 25 Amp rating protects branch circuits and equipment while supporting robust load needs in commercial and light industrial environments.
• 480V capacity aligns with common high-voltage panelboard and distribution setups, helping you maintain compliance and system integrity.
• Original part compatibility by matching the GHB3025 specification ensures BOM alignment, simplifying inventory management and retrofit projects.
• Trusted Eaton Cutler-Hammer engineering means proven performance, consistent trip characteristics, and long-term reliability in critical power applications.
• Availability through AmpState, making it easy to source exact replacements when you need them most.

Ideal use cases

• Replacing failed or discontinued breakers in legacy panelboards and load centers without reconfiguring the distribution layout.
• Stocking spares for facilities with 480V three-phase distributions to minimize downtime during outages or routine maintenance.
• Engineering retrofits where maintaining the original BOM is essential for compliance and procurement efficiency.

Why this unit stands out — unlike generic replacements, the GHB3025 is a purpose-built bolt-on breaker that preserves original electrical architecture. Its 3-pole, 25A/480V specification is tuned for dependable protection in demanding environments, helping prevent nuisance trips while delivering precise, predictable performance under normal and fault conditions.

Practical installation tips

• Verify that your panelboard or distribution equipment supports a bolt-on GHB-series breaker and matches the 3P, 480V configuration.
• Use the recommended torque and mounting procedure for secure bus-bar interface and reliable trip operation.
• Keep a dedicated spare on hand for rapid replacement and minimal system downtime.
