Eaton KCDPLB Circuit Breaker, 400A, 3-Pole, 600V

Eaton KCDPLB Circuit Breaker — 400 A, 3-Pole, 600 V

The Eaton KCDPLB is a robust circuit breaker engineered for industrial electrical service, maintenance, and replacement projects. With a solid 400 amp rating and a 3-pole configuration, it delivers reliable three-phase protection for demanding power distribution systems up to 600 volts. Use the part number to confirm compatibility with your specific application and Eaton panel lineup.

• Amperage: 400 A
• Poles: 3
• Voltage: 600 V
• Part Number: KCDPLB

Why this matters in the field: a properly matched circuit breaker prevents costly equipment damage and unscheduled downtime by interrupting fault currents and protecting feeders, motors, and other critical loads in heavy-duty environments. The 3-pole design ensures balanced protection across all three phases, helping maintain system stability even during fault events.

Ideal use cases include:

• New installations in industrial facilities that require reliable three-phase, 600V protection
• Maintenance and replacement projects where existing Eaton equipment needs an exact, drop-in fit
• System upgrades that demand a proven, field-compatible 400 A breaker to match existing protection schemes

Compatibility and setup notes: verify fit by part number and application requirements. If you’re unsure about exact compatibility, send a message and we’ll assist with matching the KCDPLB to your Eaton system and intended use.

With the Eaton KCDPLB, you get a purpose-built solution tailored for industrial power distribution—designed to install quickly, function reliably in challenging environments, and keep critical processes running smoothly.
