Eaton FDC3110L - 110 A, 600 V, 3-Pole Circuit Breaker | AmpState

Meet the Eaton FDC3110L — a compact, trusted 3-pole molded case circuit breaker designed to protect your panelboards and loadcenters with precise, dependable overcurrent and short-circuit protection. With a 110 A rating and a 600 V capacity, this breaker is built to handle the demands of modern electrical installations while preserving valuable panel space.

Overview

Engineered for reliable performance in residential, commercial, and light industrial environments, the FDC3110L pairs a space-efficient molded case design with a thermal-magnetic trip unit. This combination delivers stable, repeatable protection against both overloads and short circuits, helping to minimize downtime and maintenance calls.

Key features

• Compact molded-case design optimizes panel layout and allows more room for ancillary components.
• Thermal-magnetic trip unit provides stable, repeatable protection response for a wide range of fault conditions.
• 3-pole configuration ideal for balanced protection in 3-phase systems and 3-wire feeders.
• 600 V maximum voltage rating suitable for common commercial and light industrial distribution applications.
• 110 A amperage rating helps coordinate protection for mid-sized branch circuits and feeders.
• OEM-compatible designed to pair with matching Eaton OEM loadcenters and panelboards for streamlined installation.
• Versatile installation supports residential, commercial, and light industrial projects—from service panels to equipment rooms.

What problems does it solve?

The FDC3110L delivers targeted protection where it matters most: it reliably interrupts fault currents and overloads before damage propagates through wiring or connected equipment. Its thermal-magnetic trip mechanism offers fast short-circuit clearing while reducing nuisance trips on normal inrush conditions, helping maintain continuity in critical circuits and protecting valuable assets.

Who is this for?

electricians, facilities managers, and electrical contractors who specify or install panelboards and loadcenters in commercial spaces, multi-family buildings, retail, and light industrial facilities. If you need a trusted, OEM-compatible 3-pole breaker with solid performance and a compact footprint, the Eaton FDC3110L is a practical choice.

Use cases and practical tips

• Install in 3-phase panelboards to protect feeders and branch circuits in commercial electrical rooms and data/tech spaces.
• Use in residential commercial-core applications where space is at a premium but dependable overcurrent protection is non-negotiable.
• Coordinate with matching Eaton OEM loadcenters to ensure seamless fit and optimal tripping characteristics across the distribution system.
• When replacing an older unit, verify the panel’s compatibility with a 3-pole, 110 A, 600 V breaker to maintain listing and warranty coverage.
• Ensure proper terminal torque and secure mounting to avoid loose connections that can lead to overheating or faults.
