Eaton Cutler-Hammer FDB3150L 150A 3P 600V Circuit Breaker | AmpState

The Eaton Cutler-Hammer FDB3150L is a purpose-built circuit breaker designed to safeguard panelboards, load centers, and electrical distribution networks. With a 150 A rating and a 3-pole configuration for 3-phase systems, this unit delivers reliable protection for up to 600 V, making it a precise, drop-in solution when a direct part-number match matters for maintenance, panel builders, or spare inventory.

Direct-part-number compatibility you can trust

• Direct compatibility with Eaton Cutler-Hammer panels minimizes mis-purchases and downtime during replacements.
• 3-pole design ensures balanced protection across all three phases in 3-phase circuits.
• 150 A rating provides solid feeder protection for a wide range of commercial and light industrial applications.
• 600 V maximum rating covers a broad spectrum of electrical distribution needs.
• Designed to integrate with panelboards and load centers within Eaton-based electrical systems, keeping protection schemes intact.

Use cases that fit real-world workflows

• Spare inventory for service teams maintaining Eaton-based installations, reducing downtime when a direct part is needed.
• Panel-building projects where a precise part-number match speeds procurement and installation.
• Refurbishment or upgrade efforts in commercial facilities with existing Eaton Cutler-Hammer infrastructure.
• Replacement in 3-phase distribution setups that operate at or below 600 V, common in industrial environments.

Why this model matters for your project
