Eaton EGS3050FFB - 50 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton EGS3050FFB is a 50A, 600V, 3-pole bolt-on molded case circuit breaker designed to shield panelboards and loadcenters from overcurrent and short-circuit events. Its secure bolt-on mounting creates a rigid, vibration-resistant bus connection, helping maintain dependable electrical performance even in environments with movement or vibration.

The thermal-magnetic trip unit delivers stable, repeatable protection by responding to both overloads and short circuits, interrupting power quickly to safeguard your wiring and connected equipment. Designed to work with matching OEM loadcenters and panelboards, this breaker integrates seamlessly into Eaton installations and replacements, reducing compatibility concerns in retrofit projects.

Ideal for residential, commercial, and light industrial applications, the EGS3050FFB provides reliable branch circuit protection for three-phase systems where a 3-pole configuration is required. It’s a practical choice when you need a robust, code-appropriate solution that stays secure under vibration and delivers consistent protection performance over time.
