Eaton GBH3030 - 30 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton GBH3030 is a compact, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch-circuit overcurrent and short-circuit protection in panelboards and load centers. With a 30A rating and 600V capacity, this breaker is built to handle the demands of modern electrical distributions in residential, commercial, and light industrial environments.

• Secure bolt-on mounting: A rigid connection to the bus bars minimizes movement and vibration, helping maintain a stable electrical path even in demanding installations.
• Thermal-magnetic trip unit: Combines precise thermal overload protection with instantaneous magnetic response for reliable protection against both sustained overloads and short circuits. The result is consistent, repeatable protection performance across varying temperatures.
• Three-pole, 30A, 600V: Ideal for three-phase panelboards and load centers, providing balanced protection for multi-wire circuits and motors in commercial or light industrial settings.
• OEM-compatible design: Engineered to mate with matching Eaton OEM load centers and panelboards, ensuring proper fitment, documented protection coordination, and straightforward replacement.
• Durable construction: Molded case design built for longevity in panels that experience routine servicing, vibration, or space constraints.
• Versatile application: Suitable for a wide range of applications—from lighting and receptacle circuits in multifamily buildings to small machinery circuits in light commercial spaces.
