Product description
Shipping
The Eaton Cutler-Hammer GHB1020 20A 1P 277V Bolt-On Circuit Breaker is built for everyday electrical work, delivering reliable overcurrent protection for panelboards, load centers, and electrical distribution systems. With a 1-pole design at 277V, it protects single-phase circuits while fitting seamlessly into existing Eaton Cutler-Hammer installations. This makes it a sensible choice for both ongoing maintenance and new-installation projects where OEM compatibility matters.
- Bolt-On mounting: fast, secure installation in compatible panels, helping you minimize downtime during replacements or upgrades.
- 20A, 1P, 277V: ideal for protecting lighting runs and small branch circuits in commercial or industrial environments that use 277V distribution.
- OEM BOM alignment: designed to align with the original part number, simplifying parts stocking and ensuring you stay on the same electrical system configuration.
- GHB1020 part lineage: a genuine Eaton Cutler-Hammer component, built to meet the expectations of panelboards and distribution setups that rely on this series.
- Availability from AmpState: easy access to this specific breaker with support options—if you’re unsure about fit, a quick message can help confirm compatibility with your panel.
This breaker is especially well-suited for replacement projects where keeping the BOM consistent is important, and for stocking spares to reduce downtime in critical electrical installations. It’s a practical choice for facilities managers, electricians, and maintenance teams maintaining commercial buildings, offices, retail spaces, or any site with 277V single-pole circuits needing dependable protection.
Key considerations: ensure your panel is compatible with bolt-on Eaton Cutler-Hammer breakers in the GHB family and that the application is within 277V single-pole protection. If you need help confirming fit or part-number compatibility, send a quick message and AmpState will assist in verifying the perfect match for your system.
