Why the GBH2090 stands out

• Secure bolt-on mounting delivers a rigid, vibration-resistant connection to bus bars, maintaining conductor integrity even in environments with equipment start-ups and movement.
• Thermal-magnetic trip unit provides stable, repeatable protection performance—thermal protection handles sustained overloads while magnetic action quickly interrupts short circuits, reducing nuisance trips and guarding wiring insulation.
• 2-pole design ensures simultaneous disconnection of both live conductors, enhancing safety for multi-wire circuits and improving coordination in panel layouts.
• 600 V rating suits commercial and light industrial applications, offering robust protection across a range of voltages and load profiles.
• OEM-compatible engineered to pair with matching Eaton OEM load centers and panelboards, enabling straightforward installation, reliable interoperability, and easier stocking of spare parts.
• Versatile use in multiple environments ideal for service upgrades, new installations, and retrofits in residential, commercial, and light industrial settings where dependable branch-circuit protection is critical.

What it protects and how it helps you

The GBH2090 acts as the first line of defense against overcurrent and short circuits on branch circuits. Its precise trip characteristics help prevent conductor insulation damage and fire hazards, while the sturdy bolt-on design minimizes connection wear over time. By choosing a breaker that matches your panel’s design and your loads, you improve long-term reliability and simplify future maintenance.
