Eaton EGB3050FFB - 50 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton EGB3050FFB is a 50A, 480V, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit overcurrent and short-circuit protection in panelboards and loadcenters. Built for commercial, industrial, and residential applications, this breaker offers robust performance in environments that demand both reliability and durability.

• Secure bolt-on mounting: a rigid, vibration-resistant bus connection that stays firmly seated even in spaces with movement or vibration, helping prevent loose contacts over time.
• Thermal-magnetic trip unit: provides stable overload protection (thermal) and fast short-circuit response (magnetic) with repeatable protection performance across varying temperatures and loads.
• Three-pole, 480V design: ideal for commercial and light industrial three-phase distribution, delivering coordinated protection across all three phases.
• OEM-compatible: engineered to fit matching Eaton OEM loadcenters and panelboards, making upgrades, retrofits, or new installations straightforward without modification.
• Versatile application: suitable for a wide range of electrical layouts—residential, commercial, and light industrial—that require reliable 480V protection and easy serviceability.
