Eaton FD3110 - 110 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton FD3110 is a 110 A, 600 V, 3-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and loadcenters. Built to withstand demanding environments, it helps guard electrical systems from overcurrent and short-circuit events with precision.

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, helping maintain reliable performance even in installations subject to movement or vibration.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining thermal (overload) sensing with magnetic (short-circuit) response for fast, consistent clearing.
• OEM-compatible designed to integrate with matching Eaton OEM load centers and panelboards for seamless replacement or expansion.
• Three-pole design supports three-phase circuits up to 600 V, making it suitable for commercial and light industrial panels as well as residential installations requiring robust three-phase protection.
