Eaton FDC3150 - 150 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Engineered for dependable protection in electrical distribution, the Eaton FDC3150 is a 150A, 600V, 3-pole bolt-on molded case circuit breaker designed to safeguard branch circuits against overcurrent and short circuits. Built to endure the demands of panelboards and loadcenters, it delivers reliable performance in residential, commercial, and light industrial environments.

Key benefits that set the FDC3150 apart

• Secure bolt-on mounting provides a rigid, vibration-resistant connection to the bus, helping maintain consistent electrical performance in installations subject to movement or vibration.
• Thermal-magnetic trip unit delivers stable, repeatable protection by automatically responding to both overload and short-circuit conditions.
• OEM-compatible design ensures smooth integration with matching load centers and panelboards from the same family, simplifying replacements and upgrades.
• Three-pole configuration supports three-phase protection, making it suitable for modern commercial and light industrial power systems.
• High-current capability with a 150A rating at up to 600V, appropriate for main or feeder protection in appropriate panel setups.

Ideal applications and use cases

• Residential and multifamily panelboards that require reliable branch-circuit protection and easy maintenance access.
• Commercial distribution panels in offices, retail spaces, and service areas where consistent trip performance matters.
• Light industrial power distribution where three-phase protection is essential for equipment reliability.
• Retrofits or replacements in OEM-specified panelboards, ensuring compatibility with existing bus connections and mounting footprints.

Installation, compatibility, and practical considerations

The bolt-on mounting style is designed for a sturdy bus connection, minimizing loosening or vibration-driven wear over time. Use with matching OEM load centers and panelboards to maintain intended protection characteristics. When selecting components for an existing system, confirm that the panelboard or loadcenter is rated for a 3-pole, 150A, 600V molded case breaker of this type, and replace like-for-like to preserve coordinated protection.
