Eaton GBH2045 - 45 A, 600 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Meet the Eaton GBH2045 — a 45A, 600V, 2-pole bolt-on molded case circuit breaker crafted for dependable branch circuit protection in panelboards and loadcenters. Designed for residential, commercial, and light industrial applications, it delivers reliable protection where it matters most.

• Bolt-on mounting provides a secure, vibration-resistant connection to the bus, minimizing movement and ensuring consistent performance in demanding environments.
• Thermal-magnetic trip unit delivers stable, repeatable protection, responding to both overloads and short circuits with precise timing across temperature variations.
• Compatibility with matching OEM loadcenters and panelboards helps simplify replacement and upgrades within Eaton’s ecosystem.
• Versatile use suitable for residential, commercial, and light industrial applications, where reliable protection and straightforward installation are priorities.

• Amperage rating: 45 A
• Voltage rating: 600 V
• Number of poles: 2
• Mounting style: Bolt-on
• Type: Thermal-magnetic molded case circuit breaker
• Part number: GBH2045
• Application: Branch circuit overcurrent and short-circuit protection

The bolt-on design isn’t just about mounting—it’s about durability in real-world spaces. In environments with vibration, equipment movement, or dense wiring, a bolt-on breaker helps maintain a solid bus connection and reduces the risk of loose connections that can lead to nuisance trips or degraded protection.

Who should consider the GBH2045?

Electricians and facilities teams upgrading or expanding panelboards and loadcenters will appreciate the GBH2045’s straightforward integration with Eaton systems. It’s an excellent choice for service upgrades, new installations in compatible panels, and retrofits where robust, long-lasting protection is essential.

Practical use cases and scenarios

• Replacing aging or failed breakers in residential or light commercial panelboards where a bolt-on solution is preferred for stability.
• Installing in new or existing Eaton loadcenters that require a 2-pole, 45 A protection device for dedicated circuits.
• Setting up branch circuits that demand reliable protection against both overloads and short circuits, with predictable trip characteristics.

Installation and compatibility notes

Ensure the panelboard or loadcenter is designed for bolt-on molded case breakers and that the GBH2045 is the correct match for your Eaton system. Follow standard safety practices and refer to the panel’s documentation for torque and mounting guidelines to maintain optimal protection performance.
